Question

See the week 12 data in Q5 for the imagery group. Run an appropriate test to examine the variance between weeks 0, 6 and 12. Which is the correct answer? A) χ²(2) = 26.96, p < .001 B) χ²(2) = 26.96, p = .000 C) χ²(2) = 0.001, p < 26.96 D) χ²(2) = 26.96, p < .005

The chi-square test is used to compare the variance between multiple groups. In this case, we are comparing the variance between weeks 0, 6, and 12. The chi-square statistic is calculated to be 26.96, and the p-value is less than .001. This means that there is a statistically significant difference in the variance between the three weeks.
