In this lesson, we will learn how to find and use the least squares regression line equation.

Students will be able to

find and interpret the equation of the least squares regression line,
use the equation of the least squares regression line to solve real-life situations,
estimate the value of or given a table of - and -values or the regression model,
find the points that lie on the same least squares regression line,
calculate the value of the regression coefficient (the slope),
identify the appropriate linear model,
calculate the least squares regression line given parts of the formula such as the standard deviation or the mean.
