How do you figure S²Within "assuming sample sizes are equal"? A)Add up the population variance estimates figured from within each group, then divide by the total number of participants B)Add up the population variance estimates figured from within each group, then divide by the number of groups C)Multiply the within-group sum of squares by the size of each sample (n) D)Divide the within-group sum of squares by the size of each sample (n)

S²Within refers to the within-group sum of squares, meaning the variation within each group. Assuming sample sizes are equal, the best way to estimate the population variance is by adding up the population variance estimates figured from within each group, then dividing by the number of groups. This is because each group's variance estimate should be equally weighted in the calculation, and the number of groups gives us an indication of how many estimates are being combined. Therefore, Choice B is the best choice.
