| Oct 13, 2017 at 1:20 | comment | added | JohnStephen.19 | yeah, all questionnaires are completed. Anyway, I just read that formula above was from Yamane and applicable for dichotomous response only and assumes 95% confidence interval and p=0.5. How do you then get the sample size if the response is polythomous and you don't know the variance? | |

I figured 173 population size is manageable already since all of them are located in the same place, and I already have all the questionnaires filled by the respondents. But, she insist that the professor wants her to perform a stratified random sampling and of course she'll only follow him/her. | |
