APPLETSOURCEDESCRIPTION
Linear FunctionsLavalAllows user to change slope and intercept of a line to visualize changes.  more
Understanding the Slope of a LineLavalShows how the slope of a line is calculated.  more
Predicting YSeeing 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 PlotJava 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 LinesRossman/Chance Applet CollectionGenerates 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 ScatterplotVirtual 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 rRice 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 DemoW.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
