APPLET | SOURCE | DESCRIPTION |
|
Linear Functions | Laval | Allows user to change slope and intercept of a line to visualize changes. more |
Understanding the Slope of a Line | Laval | Shows how the slope of a line is calculated. more |
Predicting Y | Seeing Statistics (McClelland) in Fundamental Statistics for the Behavioral Sciences (Howell) | With sliders, users can change slope, intercept and x value to see visually and algebraically the predicted y value. more |
Regression Plot | Java Applets for the Visualization of Statistical Concepts (VESTAC) | Generates multiple samples of regression lines for user-specified population parameters and sample size, displays sample points and regression lines on a plot along with true line. Other applets show this output plus Histograms of Slope and Intercept, Histograms of MSR, MSE, and F, and Residual and normal probability plots. more |
Sampling Regression Lines | Rossman/Chance Applet Collection | Generates multiple samples/regression lines for user specified population parameters and sample sizes and displays sample points and regression lines on a single plot along with true line. more |
Interactive Scatterplot | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Shows regression line and mean x and y and calculates coefficients of regression line, correlation and covariance as users place points on a scatterplot. NOTE: xhtml files may not run in all browsers. more |
Components of r | Rice Virtual Lab in Statistics (Lane) | Shows how data sets would look and illustrates effects on error and correlation as users change values for slope, standard error of the estimate, and/or the standard deviation of X, can also animate changes. more |
Correlation and Regression Demo | W.H. Freeman & Co. | Users add data to a scatterplot and then try to draw the regression line, guided by a bar display that shows how much more error the user line has compared to the least squares line. more |
