Masculine-themed words (such as competitive, independent, analyze, strong) are commonly used in job recruitment materials especially for job advertisements in male-dominated areas (Gaucher, Friesen, & Kay, 2011). The same study found that those words also make the jobs less appealing to women. In a similar study, female participants were asked to read a series of job advertisements and then rate how interesting or appealing the job appeared to be. Half of the advertisements were constructed to include several masculine-themed words and the others were worded neutrally. The average rating for each type of advertisement was obtained for each participant. For
n
= 25 participants, the mean difference between the two types of advertisements is
M_D

= 1.32 points (neutral ads rated higher) with
SS
= 150 for the difference scores.

1. Is this result sufficient to conclude that there is a significant difference in the ratings for the two types of advertisements? Use a two-tailed test with  = .05.


2. Compute
   r
   ²
   to measure the size of the treatment effect.


3. Write a sentence describing the outcome of the hypothesis test and the measure of effect size as it would appear in a research report.
