A researcher wants to know if there is a difference between 12th graders and 9th graders on the ABC memory test. What is the direction for this research hypothesis?

12th graders will score higher than the 9th graders on the ABC memory test

Explanation:

A directional hypothesis can be explained as a prediction made by a researcher regarding a difference between two variables or groups of a population. In this case,  one can predict the direction based on some facts like past research, accepted theory and extensive experience.

In conclusion, the researcher will be able to know the difference in the 12th graders and 9th graders through the directional hypothesis, which will help him to find out that, the 12th graders will score higher than the 9th graders on the ABC memory test based on the experience they have gathered so far.
