“What is Hypothesis Testing?”

Hypothesis testing is a method used in statistics to see if enough data or evidence is valid enough to create conclusions over certain populations.

The purpose of the statistical method is to test whether the data can be approved or denied. Samples are examined in order to see if enough evidence can be plausible in order to create a graph.
