Decision Tree for Statistical Tests

Students, who study some subject about statistics, have often problems with choosing a proper statistical test for their task. To select a proper test, you need to consider following facts:

  • the hypothesis which you need to test,
  • the structure of your data (do you have one sample from one population, two samples from two populations, or even more?),
  • your knowledge about population(s) (like population distribution type, variance etc.).

I have created a decision tree in iBokse application to make these decisions easier for you. You can open the tree by clicking on a picture below.

iBokse is a very intuitive application. To go through the try just click on yellow answers to blue questions. Green fields contain solution – statistical tests which may be the right one for your hypothesis. However, statistics is quite complicated science. This tree only gives you a clue to select a proper test. The test but can be the right one, especially for university or college basic statistics subjects.

I would like to write more articles about statistics so I will provide links to my articles to the tree.
