Which Statistics Test?

Answer a few questions to find the right statistical test for your data.

Question 1

What are you trying to do with your data?

Not sure about your data?

  • Normal distribution: If your data looks like a bell curve, it's probably normal
  • Paired vs Independent: Same people measured twice = paired. Different people = independent.
  • Continuous vs Categorical: Numbers (height, weight) = continuous. Categories (yes/no, colors) = categorical.
