What is post-hoc tests correct for alpha inflation (q) from multiple tests?
q means
What is alpha inflation?
Name the two points about F-ratio
1. in order for the F-ratio to be significant, it must be substantially greater than 1
2. if an F-ratio is approximately 1, then the between-groups variance equals the within-groups variance, and there is no effect of the independent variable
