Definitions:

Null Hypothesis

A statistical hypothesis that assumes there is no significant difference or effect, serving as a default position until evidence suggests otherwise.

Independent Samples

Independent samples refer to sets of data collected from distinct, non-overlapping groups or populations, where the performance or measurement in one group does not influence the other.

Population Means

The average values of a particular variable for all individuals within a population.

Pooled-variances T-test

A statistical test applied to compare the means of two independent samples, especially when the two samples have the same variance.
