Sample Size Requirement

The sample size requirement is based on obtaining an observed power of 0.80, under the assumption that the significance level will be set at alpha = 0.05, and that the estimated effect size is medium.

For research questions 1 and 3, an ANOVA with a factor has 3 levels will be performed. Under the assumption of medium effect size and alpha = 0.05, it is found that the required total sample size is N = 159 , which means that each group needs a sample size of n ₁ = n ₂ = n ₃ = 53.
