Assuming that there is a 5point difference between the two s

Assuming that there is a 5-point difference between the two sample means, which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic?

Small sample sizes and large sample variances

Large sample sizes and large sample variances

Small sample sizes and small sample variances

Large sample sizes and small sample variances

Solution

The answer is d. Large sample size and small sample variances.

When we increase sample size variation reduces and we ge better results. So large sample size with small sample varinces gives good values for t statisic.
