A researcher studied the flexibility of 10 women in an aerobic exercise class, 10 women in a modern dance class, and a control group of 10 women. One measurement she made was on the degree of spinal extension. Summary statistics for the data are given in Table 1 below. We would like to see if there is a significant difference among the three groups of women with respect to flexibility. Table 1: Descriptive Statistics accompanying the flexibility study Group n xbar s^2 Aerobics 10 22.8 3.57 Modern Dance 10 21.3 4.41 Control 10 24.2 3.84 What is the Factor in this study? a. Spinal Extention b. Exercise Type c. Flexibility d. Aerobics
