Most dissertations require you (the student) to determine, a priori, the sample size for your study. The number of participants needed depend on several factors. These factors include the power for your study (typically .80), the effect size, and the alpha (typically .05). Effect sizes (small, medium, and large) tell you the strength or importance of a particular relationship, and are unique to the type of statistical analysis that you want to conduct. For any type of analysis—regression, ANOVA, chi-square, t-test, structural equation modeling, timeseries, cluster analysis—we can assist with a sample size determination. For a select group of analysis, sample size can be determined and written up with references using our online sample size tool for FREE.
