β

Often used to represent the slope coefficient in linear regression analysis, indicating the change in the dependent variable for a one-unit change in an independent variable.

Probability

The measure of the likelihood that a particular event will occur, expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty.

Critical Value

A threshold in hypothesis testing, which the test statistic must exceed in order to reject the null hypothesis, indicating a statistically significant result.
