Linear Regression Applet
Use this applet to model linear regression.

Interactive Applet: Simple Linear Regression
This applet is designed to help students visualize and manipulate a simple linear regression line and calculates error for data sets.

Scatterplots
This applet lets you study the relationship between pairs of variables using scatterplots, the correlation coefficient, the graph of averages, linear regression, and residual plots.

Regression Line and Correlation
Here are interactive computerbased tools providing students with the opportunity to easily investigate the relationship between a set of data points and a curve used to fit the data points. Four lessons are included.

Correlation Coefficient
See this explanation about correlation coefficient and how to calculate it stepbystep.

Journal of Online Mathematics and Applications
This page teaches novice learners to find the linear mathematical model to fit the data. It also teaches how to detect and deal with outlier data.

Correlation
This interactive tool helps students explore the relationship between the correlation coefficient of a data set and its graph. Fit a line to the data and compare the leastsquares fit line.

Simple Linear Regression
This page explains concepts of simple linear regression and how to plot data to show the linear relationship.

Linear Regression
Students can input data and this interactive tool will draw the regression line automatically.

Understanding the LeastSquares Regression Line with a Visual Model
Here is an example teaching students to use three methods for measuring how well a linear model fits a set of data points.

Linear Regression
Here is a comprehensive introduction to linear regression. Students will learn concepts such as slop and intercept, how to measure the goodnessoffit of linear regression, and also the confidence interval of a regression line.
