PSY-RSS07 Sample Size, Effect Size & Power Analysis0.5 semester credits
The goal of this Research Skills Seminar is to introduce students to power analysis. Students will learn the relationships between power, effect size, Type I and II error and sample size. The Seminar requires the use of both SPSS and G-Power statistical software. At the conclusion of the seminar students will be able to determine appropriate sample sizes for a variety of research designs and statistical analyses, and be able to write a scientifically supportable sample size estimate for a grant proposal or dissertation. Students will understand the concept of power and its relationship to effect size and sample size. Students will have a clear understanding of the difference between “effect size” and “statistical significance.”
