Objectives This study expands upon Weisburd’s work (1993) by reexamining the relationship between sample size and statistical power in criminological experiments. This inquiry, now known as the Weisburd paradox, postulates that increasing the sample size of experiments does not always lead to increases in statistical power. The current research also begins to explore the potential sources of the Weisburd paradox.
