Thus, the ANOVA helps in understanding if two groups with similar mean scores also share estimates of variance or whether the groups are genuinely different in the way the scores vary within the group.
The ANOVA can be used to verify the differences among groups’ performance in different settings. For example, it could be used to verify which of different mnemonic devices are useful for a particular subject. In order to do so, it is possible to choose two or three mnemonic devices and ask different groups of students to use one device each while studying for a mock test. A control group could be asked to study without using any mnemonic devices to serve as a control group. After the test, the scores for each group may be collected, and by using the ANOVA it would be possible to see if the groups’ variance is similar or different from that of the others. For this study, the type of mnemonic device used would be the independent variable and the scores (performance) on the mock test would be the dependent variable.
A researcher compares mens and womens attitudes toward "road rage." Specifically, college students are asked to read a brief scenario describing a road rage incident in which a driver of a car attempts to scare a bicycle rider who accidentally cut across his path. The driver aims his car at the bicyclist and the bicycle rider, in an attempt to get out of the way, falls and gets hurt. Men and women rate how much they are disturbed by the drivers reaction using a 10-point scale (1 = not disturbed at all, 10 = very disturbed). The mean for men was 7.4 and the mean rating for women was 8.6. A t-test for independent groups indicated the following result: t (28) = 2.76, p = .01. Answer the following questions about the results of this hypothetical experiment.
The p value shows that the chances of the observed difference between the ratings of men and
