Key Concepts

Type I Error

A Type I error occurs when a true null hypothesis is incorrectly rejected; this means a conclusion is drawn that an effect or difference exists when in reality there is none.

Type II Error

A Type II error happens when a false null hypothesis is not rejected; this means failing to detect an effect or difference that actually exists.

Hypothesis Testing

Hypothesis testing is a statistical method used to make decisions or inferences about population parameters based on sample data, determining whether the evidence is strong enough to reject a presumed null hypothesis.

Null Hypothesis

The null hypothesis is a default baseline assumption in hypothesis testing that typically asserts there is no effect or no difference, and it is the hypothesis that is tested for possible rejection.
