Question

If other factors are held constant, which of the following sets of data is most likely to produce a significant mean difference? A sample mean difference of 5 points with n = 5 for both samples A sample mean difference of 5 points with n = 10 for both samples A sample mean difference of 10 points with n = 5 for both samples A sample mean difference of 10 points with n = 10 for both samples One sample has n = 7 scores with SS = 40, and a second sample has n = 5 scores with SS = 80. The pooled variance for these two samples is 120/10 = 12. True False

Explanation / Answer

Question19:

The correct option is D

Explanation:
