An ANOVA procedure is used for data that was obtained from four sample groups each comprised of five observations. The degrees of freedom for the critical value of F areGroup of answer choices3 and 163 and 193 and 204 and 17
Solution
The degrees of freedom for an ANOVA test are calculated based on the number of groups and the total number of observations.
The degrees of freedom between groups (df1) is calculated as the number of groups minus 1. In this case, there are 4 groups, so df1 = 4 - 1 = 3.
The degrees of freedom within groups (df2) is calculated as the total number of observations minus the number of groups. In this case, there are 4 groups each with 5 observations, so the total number of observations is 4*5 = 20. Therefore, df2 = 20 - 4 = 16.
So, the degrees of freedom for the critical value of F are 3 and 16.
