| APPLET | SOURCE | DESCRIPTION |
|
| Linear Regression Applet | Exner | Users can add data to a scatterplot and then try to draw the regression line, guided by a bar display that shows how much error the user line has. more |
| Regression Applet | Statistical Java (Dorai-Raj, Anderson-Cook, Robinson) | Creates sample data with user specified slope and intercept, users try to position the "best" line, guided by a display that shows the error of the current line as well as the least squares line, with option to display actual regression line. more |
| Visual Fit | Taur, McCulloch | Generates samples of data displayed on scatterplot, user tries to position the "best" line, guided by a display that shows the error, options to display actual regression line and population line, nonlinear models also available. more |
| Regression by Eye | Rice Virtual Lab in Statistics (Lane) | User attempts to draw regression line and guess correlation coefficient of random data sets based on scatterplots and MSE of their line compared to minimum before applet reveals answers. more |
| Interactive exercise on linear regression and analysis of variance | Economics Home Page, Univ. of Michigan-Dearborn | Walks through process of evaluating user's estimate of best line through three points and comparing to best fit line using SSE, SSR, and r squared. more |
| Simple Regression Applet | Seeing Statistics (McClelland) in Just the Essentials of Elementary Statistics (Johnson, Kuby) | User tries to position the "best" line through a data set, guided by a display that shows the error. more |
| Linear Regression | Java Demos for Probability and Statistics (Stanton) | Draws regression line as users place points on a plot, shows residuals, sample statistics, coefficient estimates, confidence intervals, ANOVA table, and visual representation of confidence and prediction bands. more |
| Understanding the Least Squares Regression Line with a Visual Model | National Council of Teachers of Mathematics, Principles & Standards for School Mathematics | Users move points or line to try to find the fit with the minimum squared errors, absolute errors, or shortest distance, includes discussion questions and guided inquiry but can also be used as a standalone applet. more |
