| 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 |
|
| LineHow | Seeing Statistics with Bolder Stats | Shows how linear equation changes as user adjusts line's slope and intercept. more |
|
| Predicting Y and LineHow | 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. 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 |
