Determine how close the line is to the scatter plot. Clear video instruction shows how to plot a scatter plot and find the best fit line using the linear regression function on a calculator. Pupils use the information from the calculator...

Regression models help make sense of statistical data and assist people in making predictions describing the world around us. A thorough video lesson discusses linear regression models and concepts related to the models, such as...

There's likely a strong correlation between watching the video and learning about causation. Scholars hear about different types of correlation and correlation coefficients through the informative YouTube video. They also see how...

How does the calculator find a regression line? Don't leave your pupils wondering! The video goes through the process of calculating a regression line algebraically. The example uses a data set and use the formula for calculating...

Video defines covariance, shows how to derive its formula, and shows how it relates to the slope of the regression line. [15:08]

Video demonstrates how to calculate the equation of the regression line from a set of 4 points. Leads up to determining the coefficient of determination or r-squared which is shown in the next video. [9:15]

Video shows using a spreadsheet to demonstrate calculating the coefficient of determination or r-squared. Also explains how to interpret the value of r-squared. [9:45]

Video reviews the basics of the regression line, then shows how the formula for the coefficient of determination or r squared is derived. Explains how to interpret the coefficient of determination. [12:41]

In this lesson, you will learn the importance of the least squares regression line by comparing residuals. [7:10]

Video shows using a spreadsheet to demonstrate calculating the coefficient of determination or r-squared. Also explains how to interpret the value of r-squared.
