What is a non-directional hypothesis?
Understand the Problem
The question is asking about the definition and characteristics of a non-directional hypothesis, which is typically used in research to state that there is a difference or relationship without specifying the direction of that difference.
Answer
A non-directional hypothesis does not predict the exact direction or nature of the relationship between the two variables, stating only that there is a difference.

More Information
A non-directional hypothesis, also known as a two-tailed hypothesis, is utilized when the researcher doesn't have a specific expectation on the direction of the effect or when previous findings are contradictory.
Tips
A common mistake is to confuse a non-directional hypothesis with a null hypothesis. While a non-directional hypothesis suggests a difference exists, it does not specify the direction, whereas a null hypothesis states that no difference exists.
