Choosing a Test

How to choose an appropriate test for answering your research question

There are two decision trees that can help you find a suitable statistical test for answering your research question.

Take a good look at your research question and hypothesis/-es. Use decision tree 1 for questions concerned with group differences. Decision tree 2 can offer guidance for questions concerned with correlation. 

Decision tree 1 (group differences)

Decision tree 1 is helpful for finding an appropriate statistical test when examining differences between groups. For instance, if your research question is concerned with the question whether men score higher/lower on a certain dependent variable than women you can use decision tree 1.

Decision tree 2 (correlation)

Decision tree 2 is helpful for finding a suitable statistical test when your research interest lies in the relations between variables. For example, if your research question is concerned with (significant) effects of certain independent variables on a dependent variable you can use decision tree 2.
