[問題] 問卷等二元式資料要怎麼算power跟樣本數
題目如下:
Please describe the sample size calculation, power anaylysis and statistical
methods to the outcomes that are commonly used in the instruments such as
questionnaire and/or subjective dichotomous response to a sample inferences
research question.
我只知道這種資料的分析方法有Chi-Square test跟logistic regression
可是power跟可達到顯著水準的樣本數要如何估算我一直找不到,
網路上有calculator,可是我需要公式,版上有高手可以指點一下嗎?
小女子無限感激
