MULTIPLY CHOICE QUIZ Question 1Which of the following conditions does not suggest the use of one-way ANOVA? the dependent variable is measured on at least an interval scale. there are two levels of the independent variable. samples are independent and randomly selected. there are unequal n’s. 5 points Question 2If we obtain a value of 1.00 when calculating an F ratio, what does this mean? We should fail to reject the null hypothesis. We should reject the null hypothesis. There was a significant effect of the independent variable. There was no sampling error in the study. 5 points Question 3The problem with testing each pair of group means by conducting three independent groups t tests is that multiple t tests increase the probability of making a _____ for at least one of the tests beyond the probability specified by the alpha level. Type II error Type I error a and b neither a nor b Question 4The variance ratio is represented as _____ variability divided by _____ variability. between-group; within group within-group; between group between-group; total within-group; total 5 points Question 5Which of the following is not an assumption of the F test? samples are independently and randomly selected. levels of the independent variable are quantitative. populations scores for each group are normally distributed. scores across populations defined by the groups have homogeneous variances. 5 points Question 6An experimenter compares 4 groups of pain patients who are administered different medications. There are 24 patients in all. SSTOTAL = 230 and SSBETWEEN = 30. Calculate F. 1.5 1.0 15 .90 5 points Question 7One-way analysis of variance is used under the same circumstances as the independent groups t test except that: the independent variable has more than two levels the independent variable is between-subjects in nature the dependent...
