Definitions:

p < .001

p < .001 indicates that the probability of the observed data, or something more extreme, assuming the null hypothesis is true, is less than 0.1%, which is considered highly statistically significant.

Within-group Variability

The measure of how much individual observations in a single group differ from each other in a dataset.

Null Hypothesis

A statement in statistics that assumes there is no significant difference or effect in a given situation, until evidence proves otherwise.

Sample Size

The number of subjects included in a study, influencing the study's ability to reliably detect effects or differences.
