Definitions:

Null Hypothesis

The presumption that there is no significant difference or effect, often used as a default hypothesis in statistical testing that the experiment aims to reject.

Alternative Hypotheses

The hypothesis that proposes there is a statistically significant difference between two parameters or that a particular parameter is significantly different from a hypothesized value.

Type II Error

The error made when failing to reject a false null hypothesis, often referred to as a "false negative".

Null Hypothesis

A statement used in statistical testing which proposes that no significant difference or effect exists between certain characteristics of a population.
