1. If other factors are held constant, how does
increasing the number of scores in each sample affect
the value of the independent samples t-statistic (also
known as the t calculated or t observed) and the
likelihood of rejecting the null hypothesis?
2. If other factors are held constant, how does
increasing the sample variance affect the value of the
independent samples t-statistic (also known as the t
calculated or t observed) and the likelihood of rejecting
the null hypothesis?

Expert Solution

Step 1

1) An increase in the number of scores in each sample:

The size of the two samples influences the magnitude of the estimated standard error in the denominator of the t statistic. As sample size increases, the value of t also increases, and the likelihood of rejecting Ho increases; however, there is little or no effect on measures of effect size.
