Definitions:

Simple Linear Regression

A statistical technique that models the relationship between two variables by fitting a linear equation to observed data, with one independent variable explaining the variation in the dependent variable.

Multiple Linear Regression

An analytical approach in statistics that uses a linear equation to define how a dependent variable is related to two or more independent variables based on observed data.

Alternative Hypothesis

A statement that contradicts the null hypothesis and is tested to determine if there is evidence to support it.

Mean Difference

Mean difference, also known as the average difference, refers to the arithmetic mean of differences between paired observations in two sample sets.
