whether the treatment effect is significant.
t =

Comparing the answers you found in the preceding two cases, how does the number of scores in the sample
influence the measures of effect size?
Increasing sample size causes
in the measures of effect size.

A random sample is obtained from a population with a mean of µ
20. After a treatment is administered to the
individuals in the sample, the sample mean is M = 21.3 with a variance of s2 = 9.
