Question
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
a.Small sample sizes and large sample variances
b.Large sample sizes and large sample variances
c.Small sample sizes and small sample variances
d.Large sample sizes and small sample variances
Explanation / Answer
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.
