Hello everyone,
I am currently researching for a standard sample size, and I would also like to know when I can stop collecting responses for a bachelor and master thesis?
- Topic: Ethnic diversity and job fulfilment
- Method: questionnaire (random sample)
There are four research questions
There are two basic approaches to determining sample size for a survey. One is to determine the confidence intervals you want for your estimates, and you can find several online sample size calculators that will lead you through the steps to do this. The other is to determine the power of the basic test (e.g., ANOVA) that you will use in your statistical analysis, and this is usually done with the g*power program, which you can also find online.
But first you need to know what you are doing
I recommend Schaefer et al. Elementary Survey Sampling a download from the z-library. At that point things will be more clear
Notice the solution will depend on a probability sample. Then head for G*power.
Best wishes David Booth
It depends on the unit of analysis and research objectives. As a researcher, what is your research approach - positivist or subjectivism? Also, what is the phenomenon you are trying to research, and in what context? What is the population of the industry/sector you are researching?
If the above questions are clear, then you can use any sample size estimation formula to determine the sample size. Online software like raosoft is readily available for such work. http://www.raosoft.com/samplesize.html?nosurvey
