Definitions:

Least Squares Line

A straight line that best fits the data points of a scatter plot, minimizing the sum of the squares of the vertical distances of the points from the line.

Covariance

Covariance is a measure that indicates the extent to which two random variables change in tandem. A positive covariance means that the variables tend to move in the same direction, while a negative covariance means they move inversely.

Least Squares Line

A straight line that minimizes the sum of the squares of the differences between observed and theoretical values.

Scatter Diagram

A graphical representation of two variables that shows how much one variable is affected by another by displaying data points on a horizontal and vertical axis.
