Comparing Many Treatments 1. Analysis of Variance gets its name from the fact that it is a statistical technique for assessing whether the variances of several groups or populations are equal. (a) True (b) False 2. One assumption for ANOVA is that the sample variances for each group must be the same. (a) True (b) False 3. Fill in the blank. One assumption for ANOVA is that the distribution of the populations from which the samples come is the distribution. (a) t (b) F (c) normal (d) uniform 4. Fill in the blank. If all the assumptions for ANOVA hold, the test-statistic calculated in ANOVA will follow the distribution. (a) t (b) F (c) normal (d) uniform 5. Fill in the blank. The null hypothesis for ANOVA states that all I means are equal to each other. The alternative hypothesis states that . (a) all I means are different from each other (b) none of the I means are equal to each other (c) not all I means are equal to each other (d) 6. Fill in the blank. The basic concept underlying ANOVA is comparing the variation between the sample means (MSB) with the random variation of the observations within the samples (MSW). To have more support for the conclusion that the population means are different, the MSB should be as compared to the MSW. (a) large (b) small 7. Fill in the blank. An ANOVA will be used to test if the average rental costs for 1- bedroom apartments for 4 cities are equal. A random sample of 16 1-bedroom apartments from each city will be selected. Respectively, the degrees of freedom for the numerator and denominator of the F -statistic are _____________. (a)
