Question: Stephens Atkins and Kingston 2009 conducted a research study demonstrating
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?

In the actual ...A population has a mean of m = 30 and a standard deviation of s = 5. a. If = points were added to every score in the population, what would be the new values for the mean and standard deviation? b. If every score in the ...Calculate SS, variance, and standard deviation for the following population of N = 6 scores: 1, 6, 10, 9, 4, 6. Calculate the mean and SS (sum of squared deviations) for each of the following samples. Based on the value for the mean, you should be able to decide which SS formula is better to use.
