Hi

I am conducting a pretest ,post test survey and there is a workshop as treatment before the post test survey.I need to know the minimum number of respondents we need for doing the analysis on the gathered data of the pretest and post test surveys.The topic is related to adoption of techniques useful in cyber security and we have 6 variables to measure.For now after conducting 3 workshops we have around 30 respondents answered both pretest and post test surveys.The problem is that our focus group is limited to cyber security students,cyber security interested people or the ones who active in this field.Plus due to Covid-19 conducting the workshop physically is not easily possible.
