Im a business student doing research on transgender/LGBT community and toilet issues. Any research papers preferably with questionnaires done on this?

515 schools to reach in 18 months

I'm interested in what current knowledge/experience is with the link between quality of responds and length of interview, from lengthy household surveys implemented face-to-face with either paper or CAPI.

Can I use non-responsive test to check bias on

1. Pre-test early response using random sampling

2. Later Response using purposive sampling

The questionaire is the same, just the selection of data is different. The population is still also the same.

I'm working with Nigeria DHS 2008 data (complex survey data) and I'm using the data analysis software available through my school  (StataIC 13). I have a large number of 'not-applicable'. I'd initially re-coded them as missing, but then ran into trouble trying to explain why I had such a large amount of missingness and still was not using multiple imputation. Because of this, I'm having a hard time describing my sample. It's also complicated by the fact that of the 33,385 women interviewed, I'm actually only interested in the married women (23,954 women) so I have to specify a sub-population in addition. When I run my logistic regression model, I end up with about 15,449 observations instead of the 23,954 I expect. I'm guessing it's because of the 8021 not-applicables but I don't know how to deal with this. (1) Would 15,449 be my sample size then, instead of the 23,954 married women that I specified? (2) Do I try to address the NAs after I have weighted and specified my subpopulation (svy, sub pop:) or is this something I would need to handle before I weight my data and specify my subpopulation (i.e., married women). (3) How do I deal with the not-applicable since I have now found that re-coding them as missing is not the way to go. (4) Would I still include the NAs as part of my sample size?  Thanks in advance for your help

I am designing a paper survey about getting customers knowledge about organic foods, why they want to buy and why they do not buy.

I understand the time constraint in supermarkets, as people are in a hurry and engaged in shopping. Hence, the questionnaire should not be long. Do you think that 3 pages , with about 20 questions ( including 5 point Likert scale ) are normal? It may take about -10 minutes to complete.

The alternative would be a simple questionnaire, but then, it is just possible for analyzing percentages ( Y/N, multiple choices).

The workload of input data is also considered.

Then should I conduct a long or brief and simple questionnaire? It's like cost/benefit analysis.

I am going to have a survey on what is the ratio of LGBTIQ population in Sri Lanka, I am bit problematic in identifying the most effective and possible sampling method for this  kind of sensitive survey study.

Hello RG!

I'm trying to make an online survey which would measure the satisfaction and importance of specific elements in higher education. 

In order to maximize the response rate I'd like to make it so that respondents (students) can evaluate every variable as easily as possible, but I just can't seem to find the tools to make that happen.

As a picture is worth a thousand words, I'll just attach one, instead of trying to explain what I'm looking for.

If anyone knows a provider that allows (if possible, for free) such questionnaires, please link me.

GoogleForms, LimeSurvey, SurveyMonkey don't seem to have that option, but I might be wrong since I'm mostly familiar only with Google's services.

Thanks!
