Theresa Adigwu Grand Canyon University HLT-362V Exercise 31 11/4/12 1. The two groups whose results are reflected by the t ratios in table 2 and 3 are the cardiovascular risk factors and the Health behaviors. 2. The t ratio in table 2 which represents the greatest relative or standardized difference between the pretest and the 3 months outcomes is the triglyceride. Yes, the t ratio is statistically significant because the difference in mean at pretest and 3 months is 164.2- 150.4 = 13.8 which is a high t pair. 3. The t ratio listed in table 3 that represents the smallest relative difference between the pretest and 3 months is exercise which is -7.75. This t ratio is statistically insignificant because it’s so small. 4. The assumptions for conducting a t-test for dependent groups in a study are 1. The distribution of scores is normal or approximately normally distributed 2. The dependent variables or variable are / is measured at interval or ratio levels.
