Definitions:

Hypotheses

Statements set up for a statistical test that express the relationship between variables. There is usually a null hypothesis (no effect) and an alternative hypothesis (effect present).

Sigma

A symbol (σ) used in statistics to represent the standard deviation of a population.

Type II Error
