Definitions:

Hypotheses

Statements or predictions that are formulated for empirical testing, representing the initial step in the scientific method.

P-value

In statistical hypothesis testing, the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct.

Hypotheses

Proposed explanations or predictions that can be tested through research and experimentation.

Null Hypotheses

A hypothesis that suggests no significant difference or effect, typically representing a default or initial assumption for statistical testing.
