in this chapter presented a repeated- measures research study demonstrating that swearing can help reduce ratings of pain (Stephens, Atkins, & Kingston, 2009). In the study, each participant was asked to plunge a hand into icy water and keep it there as long as the pain would allow. In one condition, the participants repeated their favorite curse words while their hands were in the water. In the other condition, the participants repeated a neutral word. In addition to lowering the participants' perception of pain, swearing also increased the amount of time that they were able to tolerate the pain. Data similar to the results obtained in the study are shown in the following table. a. Do these data indicate a significant difference in pain tolerance between the two conditions? Use a two-tailed test with a = .05. b. Compute r, the percentage of variance accounted for, to measure the size of the treatment effect. c. Write a sentence demonstrating how the results of the hypothesis test and the measure of effect size would appear in a research report.

can help reduce ratings of pain (Stephens, Atkins, &
Kingston, 2009). In the study, each participant v
Kingston, 2009). In the study, each participant was
asked to plunge a hand into icy water and keep it there
as long as the pain would allow. In one condition, the
participants repeated their favorite curse words while
their hands were in the water. In the other condition,
the participants repeated a neutral word. In addition to
lowering the participants' perception of pain, swearing
also increased the amount of time that they were able to
tolerate the pain. Data similar to the results obtained in
the study are shown in the following table.
a. Do these data indicate a significant difference in
pain tolerance between the two conditions? Use a
two-tailed test with a = .05.

c. Write a sentence demonstrating how the results of
the hypothesis test and the measure of effect size
would appear in a research report.
