Statistical tests work by calculating a test statistic – a number that describes how much the relationship between variables in your test differs from the null hypothesis of no relationship. It then calculates a p value (probability value). The p-value estimates how likely it is that you would see the difference described by the test statistic if t...
You can perform statistical tests on data that have been collected in a statistically valid manner – either through an experiment, or through observations made using probability sampling methods. For a statistical test to be valid, your sample size needs to be large enough to approximate the true distribution of the population being studied. To det...
Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests. The most common types of parametric test include regression tests, comparison tests, and correlation tests.
Non-parametric tests don’t make as many assumptions about the data, and are useful when one or more of the common statistical assumptions are violated. However, the inferences they make aren’t as strong as with parametric tests.
This flowchart helps you choose among parametric tests. For nonparametric alternatives, check the table above.

What is a Statistical Relationship? Relationships in probability and statistics can generally be one of three things: deterministic, random, or statistical. A statistical relationship is a mixture of deterministic and random relationships. A deterministic relationship involves an exact relationship between two variables. For example, let’s ...

Before we dig into the methods of simple linear regression, we need to distinguish between two different type of relationships, namely: deterministic relationships; statistical relationships; As we'll soon see, simple linear regression concerns statistical relationships.
