Masculine-themed words are commonly used in job recruitment
materials, especially for job advertisements in male-dominated
fields. The sample study found that these words also make the jobs
less attractive to women. In a study, women were asked to read a
series of job advertisements and rate how interesting or appealing
jobs appeared to be. Half of the advertisements were constructed
with more masculine-themed words and half were worded neutrally.
The average rating for each type of advertisement was obtained for
each participant. For n = 25 participants, the mean of the
differences between the two types of advertisements is MD = 1.32
points (neutral ads rated higher) with SS = 150 for the difference
scores.
a. Is this result significant to conclude women found the job
advertisements with more masculine-themed words as less attractive
jobs? Use a = .05 (Make sure you do the whole process for
conducting a hypothesis test)
b. Calculate r2 to measure the effect size.
c. Create a 95% confidence interval.
