Non-directional Hypothesis

A hypothesis that does not predict a specific direction of the relationship between variables. It simply states that there is a relationship.

Alternative Hypothesis

A hypothesis that predicts a relationship between variables. It states that there is a connection and possibly suggests how they are related.

Null Hypothesis

A hypothesis that states there is no relationship or difference between variables. It is often the opposite of the alternative hypothesis.

Hypothesis Types

Non-directional hypothesis: does not specify the direction or presence of a relationship between variables.
Alternative hypothesis (research hypothesis): predicts a relationship among variables.
Null hypothesis: states there is no relationship between variables.
