Question

If other factors are held constant, how does an increase in the number of scores in each sample influence the value of the independent-measures t statistic and the likelihood of rejecting the null hypothesis?

A. The value of t decreases, and the likelihood of rejecting H0 increases.

B. The value of t increases, and the likelihood of rejecting H0 decreases.

C. The value of t increases, and the likelihood of rejecting H0 increases.

D. The value of t decreases, and the likelihood of rejecting H0 decreases.

Explanation / Answer

As we increase the sample size, the standard error decreases which result into the increase in t value and an increased likelihood of rejecting Ho.

Hence,

Option C is correct.
