A nondirectional hypothesis does not make a specific prediction about the direction of the relationship between the variables being studied. Options A and C both make directional predictions (i.e., that there will be no differences or that one group will have lower scores), whereas option B makes a specific prediction that the group taught the summarizing strategy will have higher scores. Option D, on the other hand, simply states that there will be differences in reading comprehension between the two groups, without specifying which group will have higher or lower scores. Therefore, option D is a nondirectional hypothesis.
