Using Gpower To Calculate Sample Size For Multiple Regression. Since we only have multiple linear regression in Gpower. The importance of sample size calculation is.
To compute statistical power for multiple regression we use Cohens effect size f2 which is defined by. F2 02 represents a small effect f2 15 represents a medium effect and f2 35 represents a large effect. I will be using GPower to get an estimate of sample size.
The importance of sample size calculation is.
Since we only have multiple linear regression in Gpower. F tests - Linear multiple regression. Compute required sample size Input. Linear regression with 4 predictors α005 power08.
