You may have to consider a series of factors for determining sample size, such as precision, population homogeneity, sampling fraction, statistical methods, and effect size and statistical power. The determination of sample size is not an easy question because it can take many factors into account.

In my evaluation project, I used a new scale that had never been tested among Hong Kong patients. Do I need to conduct a factor analysis before data analysis?
