How many participants were included in Bocchiaro's final sample?

The correct answer is: 149

The final sample of participants in Bocchiaro's study consisted of 149 individuals. This study, known for investigating the concepts of obedience, disobedience, and whistleblowing in a controlled experimental setting, utilized a subject pool that was carefully selected to ensure the validity and reliability of its findings. The choice of 149 participants derives from a combination of practical considerations and methodological rigor. Bocchiaro aimed for a sufficient sample size to draw meaningful conclusions from the data while also accommodating logistical factors such as participant recruitment and the experimental design. In terms of study design, Bocchiaro's research included a preliminary phase with a larger participant pool, but ultimately, 149 completed the necessary tasks for the analysis. This number reflects the careful balance researchers often seek between ideal sample sizes for statistical power and the realities of conducting experiments with human subjects.
