The degrees of freedom between groups (dfBG) provide an indication of the number of groups being compared. This is important in calculating the F-ratio in analysis of variance (ANOVA) and determining the statistical significance of any differences between these groups. The degrees of freedom within groups (dfWG) provide an indication of the sample size, but this is not as important in determining the F-ratio as the number of groups being compared. The independent variable is not directly related to degrees of freedom. The F-ratio can be large or small regardless of the degrees of freedom, so dfWG does not provide an indication of this.
