Determine the G*Power Analysis
Determine the G*Power Analysis on the target population of 51 students participating in a study.
Target Population
The study used a G power analysis to determine the required sample size. The study parameters were derived from the methodology section, where the study design had already determined a within-subjects t-test to be appropriate.
As such, the conditions entered into the G power analysis calculator were as follows. The test family was a t-test with a statistical test selection of “Means: Difference between two dependent means (matched pairs).”
This selection reflected that the study aimed to measure the difference between two variables within the same population over time. The type of power analysis selected was the a-prior type as we wished to determine sample size with values of alpha, power, and effect provided.
The tails section had the value one selected as the study has a directional hypothesis that the students will portray a positive response to the educational intervention (Rafati et al., 2017).
