Q

What is an Alternative Hypothesis?

A

There is a difference or relationship between variables (e.g., men and women are not equally intelligent or women are more intelligent than men).

An alternative hypothesis is sometimes referred to as the experimental hypothesis. However, this is only the case when using an experiment as a research method.

An alternative hypothesis is sometimes referred to as the correlational hypothesis. However, this is only the case when using a correlation as a research method.
