Definitions:

Null Hypothesis

A statistical hypothesis that assumes no significant difference or effect exists among the variables being studied.

Type I Error

A Type I Error occurs when a true null hypothesis is incorrectly rejected, often referred to as a "false positive."

Type II Error

A statistical error made when failing to reject a false null hypothesis, also known as a false negative.

Null Hypothesis

is a default hypothesis that there is no significant difference or effect.
