Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
We are able to detect an effect size of 0.42 standard deviations (power = 80% and alpha = 0.05).
We expect that including parent characteristics will enhance the statistical power.
|
After
We are able to detect an effect size of 0.57 standard deviations (power = 80% and alpha = 0.05).
We expect that including parent characteristics will enhance the statistical power.
