|
Line of Best Fit | National Council of Teachers of Mathematics, Illuminations | Users can place points on a scatterplot and guess at the best fit line before showing actual regression line and correlation, can also move or delete points. more |
Correlation & Regression/ WISE Regression Applet | WISE (Web Interface for Statistics Education) | Shows changes in the regression line, errors, squared errors, r squared, and ANOVA table as users move points on a scatterplot. more |
Put Points | istics.net, (Marden) | Shows effects on the correlation, regression line and residuals as user adds or erases points. more |
Regression Applet | West | Shows effects on regression line as users place an additional point on a scatterplot. more |
Simple Best Fit Line | Wolfram Demonstrations Project | Shows effects on regression line as users move or omit one of six points on a scatterplot. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. more |
Simple Linear Regression | Interactive Business Statistics (Lind, Marchal, Wathen) | Users drag points on a scatterplot for one of two sample data sets as calculations of predictions, residuals and regression line are instantly updated. more |
Leverage | Dept of Statistics, Texas A&M University | Shows effects on regression line as users adjust location of two points (one with moderate X and one that is outlier in the X direction) to extreme values. more |
Influential Observations | Seeing Statistics (McClelland) in Fundamental Statistics for the Behavioral Sciences (Howell) | Shows effects on regression line and correlation as users delete points. more |
