Definitions:

Uniformly Distributed

Describes a distribution where all outcomes are equally likely, or a variable where all intervals of the same length have the same probability.

Level Of Significance

The threshold below which a result is considered statistically significant, often set at a rate like 5%, indicating the probability of rejecting a true null hypothesis.

Null Hypothesis

The null hypothesis is a type of hypothesis used in statistics that proposes there is no statistical significance in a set of given observations, serving as a default position until evidence suggests otherwise.

Hypotheses

Statements or predictions that can be tested through scientific research or statistical analysis to determine their validity.
