Hello all, this is the first time when I am starting a string and it’s pleasant to see that there are other people having similar issues. In this way, I’ll come directly to the point, I am having a few troubles getting my head around statistics and methodology.
I have studied a considerable amount of books and settled on my methods yet the barrier is picking the suitable statistical test and the sample size. I am considering directing survey with basic random method and afterwards doing regression analysis as it would be most reasonable according to my research area. Yet, how would I do the power analysis and pick the sample size? It’s extremely confusing.

Find an online calculator for selecting the sample size. You can find it on google easily by typing ‘online power/sample size calculator’ then you will find a whole load of different tools.
