Definitions:

T Procedure

A statistical methodology employing the t-distribution to estimate population parameters, assess hypotheses, or construct confidence intervals, typically used when the sample size is small and population variance is unknown.

Null Hypothesis

A default hypothesis that there is no significant difference or effect, serving as the assumption to be tested in a statistical analysis.

Outlier

An observation in a data set that is significantly distant from other observations, indicating a variance from normal behavior.

Median

The middle value in a data set, which divides the distribution into two equal parts, ensuring that half of the data points are below it and half are above.
