Remaining Analyses Part 5

I’ve got the power


I added a section to my boxplot R script for power analyses. I did two things: 1) calculate the power of my experimental design based on theoretical effect sizes and 2) calculated the detectable effect sized based on theoretical power values. To do this, I used the pwr R package.

Conclusion: I can detect a variety of effect sizes at very low power
