Question

As noted on page 275, when the two population means are equal, the estimated standard error for the indepen- dent-measures t test provides a measure of how much difference to expect between two sample means. For each of the following situations, assume that m1 5 m2 and calculate how much difference should be expected between the two sample means.

One sample has n 5 6 scores with SS 5 70 and the second sample has n 5 10 scores with SS 5 140.
One sample has n 5 6 scores with SS 5 310 and the

second sample has n 5 10 scores with SS 5 530.
In Part b, the samples have larger variability (big- ger SS values) than in Part a, but the sample sizes are unchanged. How does larger variability affect

the magnitude of the standard error for the sample mean difference?
