Which of the following statements about the assumption of sphericity is NOT true?It is automatically met when an independent variable has only two levelsIt is the repeated measures equivalent of homogeneity of variancesIt is tested using Mauchley's test in SPSSIt is tested using Levene's test in SPSSQuestion 9

What assumption(s) must be met to conduct an independent-samples t-test? A. There is equal variance in scores between the groups. B. The data from the dependent variable must be normally distributed. C. The data from the dependent variable must be interval or ratio. D. All of these

Which one of the following statements are true about a 2-Sample t-test? It is used to compare differences between two group medians The variances of the two samples are statistically different.
