Textbook Problem

Stephens, Atkins, and Kingston (2009) conducted a research study demonstrating that swearing can help reduce pain. 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 repeatedly yelled their favorite curse words while their hands were in the water. In the other condition the participants repeated a neu­tral word. Data similar to the results obtained in the study are shown in the following table. Calculate the mean number of seconds that the participants could tolerate the pain for each of the two treatment conditions. Does it appear that swearing helped with pain tolerance?

Amount of Time (in seconds)
Participant Swear Words Neutral Words
1 94 59
2 70 61
3 52 47
4 83 60
5 46 35
6 117 92
7 69 53
8 39 30
9 51 56
10 73 61
