Once we have collected our data, we want to know how to interpret the experimental results. We do this by considering three separate hypotheses:

1 Null hypothesis—This is a statistical hypothesis that is tested to determine if there are differences between the experimental and control groups. Part of this statistical procedure is to ask the question of whether our results could have happened by chance.

2 Confound hypothesis—This is a conceptual question that asks if our results could be the result of a factor other than the IV.

3 Research hypothesis—This asks the question of whether our results are related to the IV.
