In doing planned comparisons, we use _________. A) the t test for independent groups, unaltered B) the t test for independent groups with MS_within in the denominator C) df equal to those of MS_within D) the t test for independent groups with MS_within in the denominator and df equal to those of MS_within

Planned comparisons require the use of the t test for independent groups with the mean square error of SSE1U1B0 (MSS1U1B0within) in the denominator and degrees of freedom equal to those of MSS1U1B0within. This is because planned comparisons involve comparing specific groups or conditions, and the MSS1U1B1withinS1U1B0 accounts for the variability within those groups or conditions. Therefore, choice D is the best option as it includes this necessary step.
