Özet

Estimation of sample size for the statistical tests is a considerable aspect of the analysis, which depends on some characteristics such as the number of group, effect size, Type I error, power and number of effects level. For example the effect size indicates the difference of the means between the lowest group and the highest group over the common standard deviation. A simulation study is performed both independent samples ANOVA and Repeated ANOVA to calculate the optimal sample size under different conditions.
