Sample Size
Posted: Tue Jul 14, 2026 2:59 pm
Hello,
I recently used Jamovi software. This is my first time using the software and I wanted to ask about the sample size.
I ran a power analysis to learn my sample size. It was a one-tailed test, and I entered a (0.05), power (80%), and effect size (0.33). It gave me a sample size N of 59.
I have been trying to learn if that my total sample size or sample size per group (e.g. N= 59, so I need 59 for Group A and 59 for Group B to a total of 118).
If you could please clarify that would be greatly appreciated.
Kindly
