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, 2010). The same study found that these 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 masculinethemed words and the others were worded neutrally.

The average rating for each type of advertisement was obtained for each participant. For n 5 25 participants, the mean difference between the two types of advertisements is MD 5 1.32 points (neutral ads rated higher) with SS 5 150 for the difference scores.

a. Is this result sufficient to conclude that there is a significant difference in the ratings for two types of advertisements? Use a two-tailed test with a 5 .05.

b. Compute r 2

to measure the size of the treatment effect.

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