" A comparative study of Language learning techniques and Vocabulary learning teqhniques in English language teaching"
pls guide me about the relevence of my topic and methodology that i should opt to conduct my research......honest suggestions will be appriciated
Relevant answer
Answer
You can conduct interviews - be they individual or focused) with a group/ or groups of learners in which you ask them about their techniques regarding language learning and vocabulary learning. In this case your study will be a qualitative one. After you collect your data, you can then analyze it thematically. Please consult the following:

Hi! My first trouble is sampling. While school teachers have a well-documented population in my country, private tutors' population is unknown. I will be focusing on just the ones whose full time profession is private tutoring. The sampling for private tutoring will be purposive or convenient. My trouble is, in order to do a comparison of school teachers and private tutors, should the sampling not be the same for both groups? Will it affect the analysis techniques used? I have heard (I am not sure) that if the population is unknown, non-parametric techniques have to used.
Kindly help.
I am leaning towards a mixed-methods approach, using both quantitative and qualitative data collection.
If anyone has any insights or reading material that can help, please share them.
Thank you.
Relevant answer
Answer
If you are planning to do quantitative analyses, the sampling methods should indeed be equivalent. The key problem is that if you use a self-recruited "convenience" sample, you have no idea what kind of biases you may be introducing.
Note also that you should have a rather large sample to conduct such a study. You can use the program G*power to estimate the sample size for a t-Test in this case, and there are several useful tutorials for this available.

Question

I'm conducting a comparative study - by way of most similar systems design - between two countries on their decentralization implementation on a service delivery and attempting herein to understand why some states succeed while others fail in that. Though the literature review I've found three explanations that largely appear to explain for why some succeed or fail; elite capture, lack of a supportive and clear regulatory and legal framework; and central government intervention.
I have those explanations, but i am somewhat unclear on how to proceed with the theory - since I don't have any like e.g., realism. How would I go about writing a theoretical framework if I have some potential explanations but no clear theory to hang onto?
Relevant answer
A general methodological approach can be proposed. Here is the study map
The assumption must be logically consistent.
The assumption should not contradict the fundamental provisions of the science in which the hypothesis is put forward (the provision of this requirement is not absolute, since in some cases it is useful to question these provisions themselves; if the fundamental provisions of science, which the proposed assumption contradicts, cannot be refuted, an assumption is made).
The assumption must be fundamentally verifiable. If an assumption cannot be verified in principle (substantiated or refuted), it is not recognized as a hypothesis.
The assumption should not contradict previously established facts, for the explanation of which it is not intended (not related to the subject area of ​​the proposed hypothesis).
The assumption must be applicable to the widest possible range of phenomena. This requirement allows one to choose the simplest from several hypotheses explaining the same range of phenomena - therefore it is often called the principle of simplicity.
The assumption must be effective in cognitive or practical terms (in particular, allowing the development or concretization of a program for further research).

We know, that we can use only validated methods for comparative studies. In our lab we have performed the validation of the dissolution method for the specific medicine. In the comparative study we used several different media, these media did not participate in our validation, exept the one for quality control. Does it mean that we have to perform full validation procedures in each media additionally?
Relevant answer
Answer
Interesting question. I agree with Andrei Blasko and Saeed Ayaz Khan . However, you did not mean a regular analytical method validation. You are dealing with dissolution kinetics. The dissolution itself will depend on the physicochemical parameters you used, so the kinetics.
You find in the literature different behavior of the same AFI, for instance losartan, in several mediums, pH, ionic strength, and solvation conditions. Therefore several other surface and chemical interactions may influence the kinetics, not the determination method itself.
For your safety, check the validation with the already used media. The kinetics of significant different media will change. Therefore, the dissolution kinetics may have different parameters that may affect or not the determination method.

I'm currently designing the study for my dissertation. Originally I was just going to design a plain phenomenological study where I select participants and conduct a structured interview with all of them and find the pattern and then discuss the final result and say how does IV impact DV based on the pattern of the qualitative data.
After talking to many professors from other psychology departments, they gave me cool suggestions saying it would be more convincing if I could conduct a comparative study where one group of participants are selected with the IV and another group of participants selected without the IV and ask these two groups the same set of interview questions and cross-compare the patterns of these two groups' interview results.
My questions are :1. Is there a specific method name for this research design? 2. How should I frame it in writing the methodology chapter if it doesn't have an already existed term?
Relevant answer
Answer
I would reconsider if you are to use qualitative, you should use a semi- or unstructured interview as your chosen research method and design, a structured interview would not be applicable as structured interviews are quantitative. It would make sense then if you are to use the quantitative method using two groups IV and non IV- could then be used in a comparative study to explain the DV. Whereas if you wish to use

I submitted three sample materials for DMA analysis. Resulting data (frequency, temperature, E', E'', dL, tanD, Ft, time) came out in excel file along with the graphs of all materials from the analyzing software which were also attached inside the excel file in a separate sheet . Upon inspection of the graphs, I noticed that unlike most DMA graphs which presents three smooth curves displaying the storage modulus, loss modulus, and loss tangent, the graphs I received has multiple curves that represent each elements to which I cannot properly interpret.
Furthermore, because I need to make a comparative study of my materials, I am required to plot the same sets of elements into one graph. As I initially plot for the storage modulus, what appeared was three zigzag lines coming to a curve instead of three smooth curves. This same curving zigzag lines were evident also as I plotted for the loss modulus and loss tangent of the sample materials.
Is the excel data and graph I received from the DMA analysis reliable? How do I properly plot the DMA data in excel or, possibly, in another software to achieve desired results? Thank you.
Attached here are the DMA graph of Sample 1, the graph for the storage modulus of Samples 1, 2, & 3, and DMA graph from Lozano-Sánchez, L., Bagudanch, I., Sustaita, A., Iturbe-Ek, J., Elizalde, L., Garcia-Romeu, M., & Elías-Zúñiga, A.

I have some experimental data about comparative study of physicochemical properties of two different food items (Two items with six parameters).
How can I determine ANOVA of my data?
Thanks in advance.
Relevant answer
Answer
Hello Md. Sabbir Hasan,
The answer depends on how much data you have. If your data consists of two cases (one each of the two food items), and you have six measurements taken from each case, I can think of no good statistical method that will give you a multivariate (six measures simultaneously) comparison...you would need replications of the two food items.
If you had, say, 20 replicates of each food type, and all 6 measures for each 40 cases, then a manova could possibly be conducted (grouping variable = food type; measured or dependent variables = the six properties). If you felt obliged to evaluate the properties individually, then a set of anovas or independent t-tests (same hypothesis either way, with only two groups) could be executed. However, the latter approach requires 6 hypothesis tests minimally, whereas the multivariate approach only requires one.
Good luck with your work.

It depends on many factors, for example: your target population, what statistic do you want to estimate, the desired margin of error and so on. I suggest you to take a quick read to sampling books, they cover a lot of examples that may be similar to your case. I would suggest Sampling Techniques by Cochran, which is quite exaustive in my opinion. Alternatively, if these books are too technical for you, search for empirical papers that cover similar issues or deepen your research of the literature, most of the time we think that there is no previous literature, but actually is only matter of searching thoroughly.

I have generated various models with an identical core of fixed covariates with each model differing only in the study covariate (a categorical variable that I change in each model by altering the cutoff values).
i want to indirectly compare the study covariates by comparing the various models.
How do i do that? Is C-Statistic an option?

Hello,
usually, We use Akaike's information criterion (AIC) to evaluate the goodness of fit,; so the model who give us the min value of AIC we choose it as best model; furthermore for effeciency we can deal with an AUC analysis.

An excellent response from Nancy - who is obviously very well positioned to respond. Mohammed - you don't state at what level your research will take place - nor your position. Are you an 'emerging' researcher and/or a Higher Degree student? If Nancy's feedback seems a little too complex - my suggestion would be a more straightforward 'narrative analysis' approach. You can adopt a 'constant comparison' approach - and look for emerging associated and non-associated themes - and look to see how they relate to your three concepts.

Why do the dentist and researcher use endodontic training blocks instead of extracted teeth for the comparative study of different endodontic files? Is there any similarity in endo training blocks and extracted teeth?
Relevant answer
Answer
I think there are two possible reasons for this:
- endodontic training blocks are all the same, i.e. it is a very standardized evaluation using such blocks.
- In many European countries (I have only experience within Europe) it is very difficult to obtain a sufficiently high number of suitable extracted teeth (less and less teeth are extracted nowadays and, in addition, the formalities, such as approval by the ethics committees, are becoming more and more complicated).
The way I see it, training blocks are the easiest (not necessarily the best) way to compare filing techniques. Even if you can't replace natural teeth with them.

How does Hofstede's theory on 6 dimensions of culture (used to compare culture to culture) speak to themes found in cultural studies and postcolonial studies literature (such as orientalism and occidentalism, stereotype)?
Hofstede is this researcher who did a research study in the workplace in 50 countries in the 70s, and he created 6 dimensions to compare the culture of one country to another such as individualism vs. collectivism, power distance (the degree to which the less powerful members of a society accept and expect that power is distributed unequally), masculinity vs. femininity (The Masculinity represents a preference in society for achievement, heroism, assertiveness, and material rewards for success. Its opposite, Femininity, stands for a preference for cooperation, modesty, caring for the weak and quality of life), etc.

I am comparing two geographical areas of different levels of social capital in Britain. I found some database to do the comparison, but the areas are different in several terms. first, one area is from the north west of England and the other one is from midlands. the two areas are different in terms of size, population, type of economy, and service sector. my question is, do these indicators should be the same to do my comparative study. for example, should the areas be similar of population?
Relevant answer
Answer
The best way to compare two areas is to live in both for at least a few months and not to merely simulate them via computing algorythms. This may seem counter-intuitive, but consider how the media distort or even ignore some place you live or have lived. Can this be because "memes" about places are being passed without enough active observers o update and correct invalid or incorrect data on those places.

I found many discrepancies in variants identification on the same strain and I would like to know if this is due to the sequencing technologies or if this is determined by a poor filtering strategy in variants identification. Could you suggest studies performed on this topic? Alternatively, is there anybody having direct experience in this topic?

Hey, We are testing a qPCR instrument that requires fairly large reactions volumes. To do some comparative studies, we simply used smaller reactions volumes when running comparative samples on a traditional qPCR instrument. However, we seem to get quite high variation between the instruments when calculating copies/µl, but almost identical concentration when it is measured in copies/rxn. The two reaction types are 30µl reaction with 6 µl DNA and a 10 µl reaction with 2 µl DNA. The components in the two reactions are the same and in the same ratio see below. 30µl reaction 10 µl reaction MM 15µl 5µl H2O 3µl 1µl Assay 6µl 2µl DNA 6µl 2µl Total 30µl 10µl Our standards are composed of synthetic DNA, for 30µl reactions we use 6x10^0-6x10^5 stds and for 10µl reactions we use 2x10^0-2x10^5.
This is how I normally would calculate absolute quantities: 1: 10^(Ct value-Intercept)/slope = Copies / rxn Then to obtain Copies/µl 2: (Copies/10 µl rxn) / (2 µl DNA/ 10 µl rxn) or (Copies/30 µl rxn) / (6 µl DNA/ 30 µl rxn) which would yield Copies/2 µl DNA or Copies/6 µl DNA. 3: Hence to obtain our copies pr. µl we would divide with 2 or 6 µl depending on which reaction volume is used.
However, I feel like something is missing or at least not accounted for. My arguments are that there are equal amounts of DNA copies (or DNA µl) per volume reaction and hence there is no difference between the reactions due to the concentration within the reaction itself. qPCR is based on fluorescence which is determined by the concentration. It is therefore not directly the absolute number of DNA template which determines the quantity but rather the concentration within the reaction. 2µl DNA / 10µl reaction volume or 6 µl DNA / 30 µl reaction volume yield the same concentration of 0,2. However, if this is correct, how to I proceed from here to calculate standardized copies/µl for both volumes?
