Definitions:

Residual Standard Deviation

A measure of the amount of variation in a set of observed values that is not explained by a statistical model, representing the standard deviation of the differences between predicted and observed values.

Regression Model

A mathematical representation used to estimate the relationship between a dependent variable and one or more independent variables.

Normally Distributed Residuals

Residuals (the differences between observed and predicted values) that are distributed according to a normal distribution, indicating a good fit for a linear model.

Normal Probability Plot

A graphical technique used to determine if a data set approximates a normal distribution, by plotting observed values against theoretically expected values in a normal distribution.
