Definitions:

β Value

In statistics, represents the type II error rate, or the probability of failing to reject a false null hypothesis; also used to denote regression coefficients in multiple regression models.

Increasing

Becoming greater or larger in quantity, size, intensity, or degree.

Standard Deviation

A figure that gauges the scatter of data points around the mean value, demonstrating the extent of dispersion.

Test Statistic

A standardized value used in statistical hypothesis testing to determine whether to reject the null hypothesis.
