The degrees of freedom between groups (dfBG) is calculated as the number of groups minus one, which is 4 - 1 = 3. The degrees of freedom within groups (dfWG) is calculated as the total sample size minus the number of groups, which is 20 - 4 = 16. The total sample size is the number of groups multiplied by the number of participants per group, which is 4 * 5 = 20.
