Answer: Use directional hypotheses

Explanation: Directional hypothesis can be defined as a probability estimation based on statistical methods made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population.

This hypothesis is usually based on past research, accepted theory, extensive experience, or literature on the topic.

It is useful to predict the direction (effect of one variable on the other as 'Positive' or 'Negative').
