Suppose you perform an ANOVA on 18 subjects divided evenly into three groups according to age.Reading speed is measured and averaged for each of the three groups.The reading speed for the Young Group is 10;for the Middle Group,12;and for the Older Group,13.Your is 9.15.This is a significant .Which of the following is the correct way to report this finding?
A)The Older Group reads significantly faster than any other group.
B)The Young Group reads significantly faster than any other group.
C)There is a significant difference between the Older Group and the Middle Group.
D)There is a significant difference among the reading speeds somewhere.

Quizplus · Accepted Answer

The significant ANOVA result indicates that there is a significant difference among the reading speeds of the three age groups. However, the ANOVA result does not provide information on which specific group(s) differ from each other. Therefore, options A, B, and C cannot be supported based on the given information. The correct way to report this finding is that there is a significant difference among the reading speeds somewhere.
