Document Summary
Paired samples t-test: home: m = 3. 19, sd = 1. 17, park: m = 3. 88, sd = 1. 15. Output: descriptive stats t(15) = -2. 03, p = . 060: conclude that dogs don"t differ signif"ly in their lvl of yappiness when at home vs when they are in the park. A researcher was interested in determining the effectiveness of different pain medications for decreasing back pain. 1 group of ps received drug a & another group received drug b.

An ind samples t-test was used to test the hypothesis that drug a would decrease pain more than would drug b (ho: Levene"stest of homogeneity of variance was not signif, so equal variances were assumed, levenef(1, 38) = 1. 22, p = . 560. It was found that the avg pain felt by ps who took.
