Explanation of properties

  • Scaling of data: One of the properties of the tests is the scale of the data, which can be interval-based, ordinal or nominal.[1] Nominal scale is also known as categorical.[2] Interval scale is also known as numerical.[2] When categorical data has only two possibilities, it is called binary or dichotomous.[3]
  • Assumptions, parametric and non-parametric: There are two groups of statistical tests, parametric and non-parametric. The choice between these two groups needs to be justified. Parametric tests assume that the data follow a particular distribution, typically a normal distribution, while non-parametric tests make no assumptions about the distribution.[4] Non-parametric tests have the advantage of being more resistant to misbehaviour of the data, such as outliers.[4] They also have the disadvantage of being less certain in the statistical estimate.[4]
  • Type of data: Statistical tests use different types of data.[3] Some tests perform univariate analysis on a single sample with a single variable. Others compare two or more paired or unpaired samples. Unpaired samples are also called independent samples. Paired samples are also called dependent. Finally, there are some statistical tests that perform analysis of relationship between multiple variables like regression.[3]
  • Number of samples: The number of samples of data.
  • Exactness: A test can be exact or be asymptotic delivering approximate results.
