Practical Issues in Calculating the Sample Size for Prevalence Studies Naing L.author Winn T.author Rusli B.N.authorThe sample size calculation for a prevalence only needs a simple formula. However, there are a number of practical issues in selecting values for the parameters required in the formula. Several practical issues are addressed and appropriate recommendations are given. The paper also suggests the application of a software calculator that checks the normal approximation assumption and incorporates finite population correction in the sample size calculation.Q Science, Computer ScienceR Medicine, Dentistry, Pharmacy, Nursing2006School of Dental Sciences, Universiti Sains MalaysiaJournal
