Definitions:

Regression Coefficients

Parameters in a regression model that represent the change in the dependent variable expected for a one-unit change in the predictor variable, holding all else constant.

Independent Variables

Variables in an analysis that are manipulated or categorized to observe their effect on the dependent variable.

T-distribution

A probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small and the population standard deviation is unknown.

Regression Coefficients

Values that represent the amount of change in the dependent variable for a one-unit change in an independent variable in a regression analysis.
