Question 1You can examine Levene's test for homogeneity to more formally test which of the following assumptions?1 pointthe assumption of errors being normally distributedthe assumption of equal variancesthe assumption of independent observationsthe assumption of treatments being randomly assigned

Researcher Quizes R Grate obtains a significant Levene’s test. What has happened? The assumption of homogeneity of variance has been violated Quizes has found out they have an inflated chance of making a Type I error Quizes’ dependent variable was measured on an interval scale The assumption of independence has been violated

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

Which of these is not an assumption of the two-sample t-test?Question 3Answera.Independenceb.Homogeneity of variancec.Normalityd.Sphericity

Only one of these statements is wrong. Which is it?Question 14Answera.A one-sample t-test assumes homogeneity of varianceb. A two-sample t-test assumes homogeneity of variancec.A one-sample t-test assumes normalityd.A paired t-test assumes normality

HOW DO YOU TEST FOR THESE ASSUMPTIONS
