Collecting Data - Science method

I'm a new student and I need ideas that help me in the future in Hematology or Blood Transfusion but I need it in a lab filed so I can collect data easily.

In large corporations characterized by a complex, multi-level organizational structure, the flow of information can be difficult. New ICT and Industry 4.0 information technologies are proving to be helpful in this regard, improving the efficiency of the flow of information flowing between departments and divisions in the corporation. One of the Industry 4.0 technologies that has recently found various new applications is artificial intelligence. Artificial intelligence technology is finding many new applications in recent years. The implementation of artificial intelligence, machine learning and other Industry 4.0 technologies into various business fields of companies, enterprises and financial institutions is associated with the increase in digitization and automation of processes carried out in business entities. For several decades, in order to refine and improve the flow of information in a corporation characterized by a complex organizational structure, integrated information systems are being implemented that informationally connect applications and programs operating within specific departments, divisions, plants, etc. in a large enterprise, company, corporation. Nowadays, a technology that can help optimize remote communication and information flow in a corporation is artificial intelligence. Artificial intelligence can help optimize information flow and data transfer within a corporation's intranet.

Besides, the technologies of Industry 4.0, including artificial intelligence, can help improve the cyber security techniques of data transfer, including that carried out in email communications.

In view of the above, I address the following question to the esteemed community of researchers and scientists:

What is your opinion on this issue?

Please answer,

I invite everyone to join the discussion,

Thank you very much,

What are the best steps to conduct a cross-sectional study? I'm planning to collect data using an electronic questionnaire.

I collected data using a constant sum scale (forced choice scale) and I need guidance on how to analyse the data.

Good afternoon,

I am thinking about how I can present the data cleaning stage of my research project. I am hesitating between generating a summary table (could be complex because it includes 16 different datasets) with a paragraph presenting the overall steps, for example, n rows were removed due to missing values, duplicated data, spelling was modified for n rows, etc. or generating a list of items (could appear redundant for the reader) for each encountered issues or checking, for example, days of the week were investigated to check that all collected data were recorded during a school day. In the article format, this stage was usually not really developed except in the data supplementary appendix due to the size of the format. I wanted to develop this section in my thesis report but I am not sure about the most appropriate format to make it clear, concise, simple to understand, and interesting for the readers. Please, could you tell me if as a reader you prefer to have a table or descriptive paragraphs or more visual elements like charts to understand how the research team cleaned the data?

Thanks in advance for all your feedback on the data cleaning oresentation

I am completing an evaluation using pre collected data from a training group which has been around for a few years. The way the data was collected was by using a questionnaire which allows for short/ medium answers.

I am unsure if a thematic analysis is the best way forward and if so I am unsure if there is a certain way that I should do it.

Thank you in advance

I have collected data through survey from in 5 point likert scale where 1 as Strongly Disagree to 5 as Strongly Agree. I have total 20 questions in 4 constructs: economy, psychology, political and social. Among 20 questions, around 8 questions are in negative statements. So, after entering all data into SPSS file; I did reverse coding for those 8 statements of negative meaning. Here, I am in confusion for the next step; that should I change these 8 negative meaning statements into positive meaning statements? If I have to change, what should be the format of sentence?

For example,

negative statement: I am a bad student.

positive statement : I am not a bad student. (option-1)

or, I am a good student. (option-2)

If I have to change the sentence, which option will be appropriate?

Thanks and regards.

Assume I collected data few at ordinal, few at interval and few at ratio scale. Now i want to consider all this in an analysis. Is it possible to do it? If possible, what kind of studies is it calls? What software facilitates this analysis? thank you for your time.

Hi all,

I'm currently trying to have an overview of existing sequences on NCBI, and I would like to look at their collection dates and locations. But I currently am only able to manually click into their BioSample page to look for this information, and it would take ages to collect this data for 4000 sequences. Is there anyway I could download this in a batch for all sequences at once?

Thanks

Hi All,

I'm an Assistant Professor from HKBU (Zhuhai campus) who is looking for one or two collaborators to work on a piece related to environmental risks (e.g., the release of radioactive water). My research mainly focuses on consumer information behavior.

Since the study is intended to be cross-cultural, I'd like to invite a scholar fluent in Korean with the resources to gather data from Korea. Ideally, I'd also like to ask another scholar who is currently or has the resources to collect data from the States. Of course, you can be both.

Also, it'd be fantastic if you are familiar with SEM.

I plan to finish the project by the end of this year, so I hope we can work efficiently. If you are interested in this opportunity, please don't hesitate to message me via ResearchGate or xiaoshanli@uic.edu.hk.

Thank you, and I look forward to hearing from you!

I have completed collecting data and upload to PLS-SEM. During analysis all the value of path coefficients became positive. Do I continue to the step or not?

I got a question when estimating sample size. After getting the theoretical sample size, it needs to consider the response rate and invalid response rate when collecting data in the study based on an online survey. So, how to determine the invalid response rate before collecting data?

Qualitative research involves non-random sampling techniques and qualitative data-collecting methods such as in-depth interviews. Can I use a mixed form here when collecting data? For example, demographic data of the sample? Are demographic data not crucial in qualitative research?

Hi,

My supervisor has suggested me to collect some extra data (around 50) to see if my previously collected data on December 2021. I have done my data analysis and the results came out fine. Should I do the extra data collection? if i do that do i need to add an extra section comparing those two datasets? Is it feasible to compare a dataset of 390 participants and 50 participants?

Please guide me.

Regards.

For example, I want to capture on Facebook all pages or accounts three months ago communicated a particular event, say an Earthquake.

Where can we collect data on swarm intelligence algorithms and optimisation work, and what software is used to mimic it?

In the case of standing in public and attempting to stop passers-by to complete a short questionnaire, what is your basic approach? In a previous life, I was a commission salesman, so I know how important it is to make the first utterance out of your mouth the right one if you want people to give you even two seconds of their time, so what tends to work best for collecting data for research? A yes-no question? An open-ended question? A statement about the weather? Asking if they have a couple minutes vs avoiding mentioning time? Here have been some of my attempts, but it's hard to gauge which works best with the few attempts I've made:

(For specifics on my current survey, it's a bunch of Likert scale questions aimed at getting opinions about bilingual signage in a small town. I'm standing in front of grocery stores to encounter people as there really aren't any other places with regular foot traffic.)

If a researcher has a hypothesis in his study, i.e., "There is no significant difference in perception of Ph.D., Masters, & bachelors students of higher education towards internet usage", and the researcher developed a Likert scale and collected data by using Google form and sending it to various WhatsApp groups through friend and colleagues circle and got one hundred fifty responses. Can these procedures, which the researcher has used in his study, meet the assumption of ANOVA to use for testing the above null hypothesis?

Another thing is, nowadays, online data collection has been very popular due to the advancement of technology, and the Google form is very general and useful also. So what kind of sampling procedure will it follow when we share it person to person and collect data? Is it scientific to use inferential statistics in the analysis of online collected data, as it may violate the assumption of random sampling?

I request the experts and experienced people and also the scholars to share their experiences related to this query.

Thank you

In the field of research, survey type research is very popular and widely used as a research method. But some times I felt that collecting data by closed ended questionnaire may lead to socially desirable responses or behavior, example - if anyone is conducting a research on "Current Status Professional Development of Secondary Teacher" and the researcher is putting questions about the activities like - Are you a enrolling in refresher courses, are you participating in seminar, workshop or Faculty development programme etc

Then the respondent here may answer in his positive side whether he/she is doing these activities or not (So these type of socially desirable behavior they are giving and happening also). It is very much affecting the authenticity of the data we got from our sample and what we report for the development of the society may be wrong and we are providing to some extend the wrong data. So how can we mitigate or limit or reduce this effect.

I need a new tool to collect data about the opinions of a sample of customers about a particular product. Need to hear your views and experiences

I am using OPENBCI 21 channel cap with Cyton and daisy board. My PHD thesis is to collect data for emotion classification using random visual stimuli. I have developed a MATLAB software to separate and label the collected data for classification. I have an issue that the data I am getting from my OPENBCI device is too noisy .I have settled everything in GUI (Smoothing On, Notch filter 50, Bandpass 5 to 50 Hz) All channels are NOT RAILED and impedance is Green with all channels though the values are high but channels are GREEN as per vendor recommendations. Can anyone guide what to do .I am also attaching the images of my Eye closed of 2 minutes data. Application of filters is in MATLAB code is not creating any difference in it.

(https://ieeexplore.ieee.org/abstract/document/9862906) papers talks about cancelling gain of differential amplifier. Can anyone that do we subtract differential gain using this formulae:

end;

If a researcher has collected data by using Google form and got the data from different universities which is scattered in the country , how can he/she state the demographic structure of the sample and what type of sampling procedure he/she will use?

I'm carrying out a longitudinal study,

For data analysis we have to collect data several times for each variable and for the same patient

I use SPSS to draw up statistical analysis and I found a difficult how I can enter data for each patient?

any suggestion to resolve this problem please ?

Dear Scholars,

I need support for my research design:

The study is Interview of faculties in first Phase and then survey in the second phase from undergraduate student.

I collected data through interview to explore the factors of a Phenomenon. After coding and thematic analysis, I collected data through survey questionnar for some of the factors of qualitative data to validate and traingulate the data. I merged the findings in discussion for both. I really need the proper design of Mixed method which cover this data collection.

I a trying to carry out a simulation of the HTL process and I am hoping to find fluid properties based on experimental data, including heat of reaction and rheology of non-newtonian behavior, etc.

Alternatively, the actual collected data that I could use to feed my simulation.

Thank you.

Different primary methods of collecting data.

I read rings on birds in a landfill for two winters. In this way, by reading codes on the rings, I got their ages from their life histories. For each species, I'd like to compare the mean age between the first winter and the second winter, in order to search for a significant difference. Which test should I use? And, should I include the rings that I read in both winters?

This a graph example. The p values and data are invented. X axis has got species names, Y the ages, whereas colours stand for the two winters in which I collected data.

Thanks in advance!

Metabolomics has emerged as an invaluable tool for prognostic and diagnostic purposes, last in the cascade of others OMICS -genomics, transcriptomics, and proteomics. Omics training usually covers experiment design, data generation, and collection, data preparation, data analysis, and the last but not the least - data interpretation.

At the end of this meticulous energy, time, and financial-consuming path, it might be totally none sense to fail to put your results into the broader biological context.

For those like me that have never been trained to interpret metabolomics data, how can we make sure to not miss important points? Is Basic knowledge in Biochemistry, Physiology, or physiopathology of the disease of your interest, enough to harness the full potential of metabolomics technologies for biomarker screening u.a?

I would like to discuss with experts out there, the most important assets for a right and successful data interpretation of metabolomics data.

Thank you for sharing your experience in the Metabolomics journey as well.

Im trying to make a webpage that makes collecting data efficiently from a person compared to pen and paper methods. What should I do? Is there a way to do this without having a a sample or like just do developer testing?

Hi, I've collected data from a strain of E.coli that has been transformed several times to produce different proteins. The strains have then been exposed to a growth limiting factor. I intend to compare the ability of the bacteria by determining the time it takes for the strains to pass the exponential growth phase threshold. How do I calculate this using OD absorbance?

I need to collect data but minimize contact between interviewer and interviewee

To give some context, I have a background in acoustics but I am now conducting research in biomedical engineering. I'm guessing the practices and requirements when measuring human participants is different, so I though I would like to ask the biomedical community for recommendations to do it right.

I will be measuring and collecting data from the heart-rate (HR) and heart-rate variability (HRV) of participants while being exposed to sound. I ensuring that everything is safe and I am in the process of obtaining ethics permission to do these experiments. No personal information of the participants will be acquired other than gender and age.

Still, what are the considerations I should have when acquiring this sort of data considering I would like to publish its results. Number of participants? What sort of pre-screening? The way data is presented? Statistical approaches for analyzing the data?

Thank you in advance!

I am doing a qualitative research with a prime purpose to develop a marketing model. For the same i have collected data via a semi structured interview. How should i proceed now with the analysis? Can anyone recommend any work for the same.

I have got a comment from a reviewer and do not know how to address it:

The authors have revised the manuscript well, but I'm still unsure about the data collection period. This study collected data in 2013-2014 which means about 9-10 years ago. And we know conditions have changed a lot after the pandemic, and the authors need to justify that this research is still applicable. The justification given is still quite dubious to me. Maybe you can include references that support that the data is still valid and reliable for analysis in your study.

Would you please mind suggesting how to respond to this comment?

We have CECIL CE 3021 uv vis spectrophotometer. Unfortunately, we are unable to run it by computer and collect data from it. Could anyone help us?

Hi everyone,

I am collecting data for my master's thesis on the low access and retention rate of women workforce in STEM and the effects of remote work. For this reason, I am conducting a survey (https://forms.office.com/e/6asy4kRJP7), and the target group are women in Germany who currently work in STEM fields and those who have changed to non-STEM jobs or have exited the labor force.

If anyone of you fits into the target group, I would appreciate it if you could participate. Also, do you have any suggestions on where else I may post it as well?

Thank you!

If I conduct a research about raising awareness about a certain disease and collect data online, from whom do I have to get the ethics approval? The participants are general population and I do not know apart from their informed consent what other ethics approval do I need and from whom. Is it the university I am affiliated do? I am not convinced because my participants are not students. Please, help!

Multiple qualitative methods were used to collect data for a PhD degree work. I would like to know if the findings can be presented as two separate chapters instead of one divided into sections. What would inform such a decision?

Data collected from social media platforms such as Facebook and Twitter raise ethical issues such as seeking consent and copyright.

I often use Likert scales to collect data on subjective perceptions. Usually, we enter positive values (e.g. 1-5, 1-7, 0-10) when performing correlation analysis/difference analysis/linear regression. But can I perform these statistical analyses if I am using a bi-level scale (-3-+3, -10-+10) that contains both positive and negative values?

I am assessing coping of father and mother by using Ways of Coping Questionnaire. I am using 2 domains of WoC ignoring other 6 domains though I have collected data for other domains too. As per my research question, I just wanted to test which coping style among the selected 2 widely used by mother and father and significant difference in their mean will tell. Though among all the domains the selected subscale mean were not greater than the other unselected one. So is it wrong to ignore other domain and use those two if can back up with the literature?

Hello, I'm currently conducting research concerning the effect of social media language on EFL students' academic writing.

Does that make my research descriptive in nature?

And I want to collect data via questionnaires and interviews, does that mean the mixed-methods approach is used?

Finally, the descriptive statistics technique (statistical analysis) is used to analyze the participants’ responses? Could you please tell me if this is accurate?

Thanks in advance.

I am collecting data for my research. My target audiences are corporate employees as well as employees working in academic field.

Kindly provide some guidance on the forums where I can paste my link to questionnaire for these target people.

My abstract has been accepted for full submission for a book chapter. This will be my first submission for peer review so I am still learning as I go.

I collected data on the topic (quantitative - structured questionnaire) and would like to include this data in the book chapter as it add value (this data and some findings where included in the abstract that was accepted).

My questions are : Can I include it as a 'case study' insert into the book chapter and what is best way/structure to do so?

Thank you for your assistance

I have collected data from 300+ studies on microplastic densities in rivers, I would like to investigate how the density varies with numeric variables (population density, Average GDP, plastic production) and categorical variables (vegetated/non-vegetated, continent, ecoregion, climatic zone).

However, when running "metamean", and using the "byvar" function I can only analyze one variable at a time. Can anyone recommend a mutivariate method so I can look at what factors are driving the microplastic variation?

Thanks

While I collected data, I've some important data in triennial (3-year interval) format. All other data in monthly format. How can I convert these to monthly in STATA or Excel?

i want to assess is there is a relationship between drop in pressure and meter inaccuracies in intermittent water supply systems

Hi,

I am learning how to critique qualitative papers and I have got 2 questions:

1) What if the researches do not state the study design (e.g., grounded theory, phenomenology etc.) that they used? what are the implications of not saying it? I know that based on the design the researchers should use specific sampling methods and specific techniques to collect data, but if they don't say which is the design is it up to me to try to figure it out? or the study loses trustworthiness?

2) Is it possible to state that data saturation has been reached without using triangulation?

thank you

Specifically, I'll be interviewing people in a community where the idea of fluid gender is likely scoffed at by most people. However, I still need to know their self-identified genders, so I have to find a way to ask without also distancing myself from them through the very act of asking. For instance, a participant might not only not believe in gender fluidity but also be insulted that I would even ask because that would imply that I can't tell if they consider themselves to be a woman or a man or something else. For those with experience in this sort of environment, how do you ask the question?

Ambient awareness is a term used by social scientists to describe a new form of peripheral social awareness. This awareness is propagated from relatively constant contact with one's friends and colleagues via social networking platforms on the Internet. To collect data i need an existing adoptable scale for my M.Phil thesis.

I want to collect data from our College students for quantitative research. The population from whom, I can collect data is 80. I would be grateful if someone answers this question: "What should be my sample size in terms of number of students?"

Dear all,

I have collected empirical data using semi-structured interview. The topic is related to the law and regulation. Now I have to start analysing the collected data. As keyword, my supervisor talked about intercoder reliability. What do you recommend also in this regard. I have no quantitve, just qualitative data. The aims of the research to determine the effect of a law on other foreign laws.

Thanks for your help in advanced.

I have collected data on a drug and patients remaining in disease-remission at 3 months, 6 months and 12 months. My data is calculated as a proportion/percentage (e.g. 33/39 patients (84.6%) in remission at 3m, 71.8% in remission at 6m, 53.8% in remission at 12m.

I would like to test if there is a significant difference between remission rates at 3m, 6m and 12m - is there a specific test that would be recommended?

Many thanks

Regards to everybody

I have another inquiry with which I hope you can assist me.

I have collected data from participants pertaining to my study issue, as well as other data, such as age and gender. These "other" information are not part of the variables; they are merely extra information.

How should this information be included in the discussion section of the study report without deviating too much from the main hypothesis? e.g. Can I indicate, for instance, that the majority of participants were between the ages of 18 and 30, and that older people may need to be included in future studies to evaluate reliability, etc.? That is, to make use of this "other" data and not only include it in the section for participants?

Thank you once again in advance for your help.

Kind regards,

Brian.

I have secondary data on sustainable energy for 35 Sub-Saharan African countries with 4 IVs and 34 sub-variables in all. I should have collected data for all the countries in the region but for incomplete data for others. I can't figure out whether the data set is enough. I ran the analysis for the available data but none of the variables contributed significantly to the DV.

I intend to survey the construction site by photogrammetry. I will use Visualsfm software to generate the point cloud.

I am working on the methodology section for my dissertation and would like to use the Early Trauma Inventory to collect data on retrospective child trauma and the developmental timing of first trauma occurrence. Ideally, I would like to collect all of my dissertation data virtually (online) but am aware of the potential challenges that can arise when collecting trauma data. I am looking for advice/tips/protocols for collecting retrospective trauma data virtually in the safest and most ethical manner.

I have collected various data from the literature on different factors that I want to use for my research.

For each factor there is not the same amount of data from the literature e.g. one factor has data from 9 different articles while another factor has data from 15 different articles. Is there any way I can give the collected data an equal weight so that I can further use it to create prior probabilities to build a Bayesian network?

Thanks in advance!
