| Summary: | 碩士 === 國立交通大學 === 管理科學系所 === 101 === In social science researches, the random effects model is commonly used and the ICC is the interclass correlation coefficient in this random effects model. It’s very complicated to use the exact method to calculate the required number of samples (subject) by given confidence interval (α), the correlation coefficient ICC (p) of the groups and the number of groups (observation). For this reason, some scholars put forward a method which use the confidence interval assigned by Z distribution in "simplified" method to estimate the required number of samples, that is to say they use the confidence interval assigned by normal distribution to approximate.
This research will compare these different large sample size simplified methods and find out the proper using time of these methods.
