I have provided four programs for downloading below. You may distribute them, but you may not charge any money for doing so. Please enclose a note telling them what the money is for. The program comes with extensive help screens, which explain basic statistical concepts at an undergraduate level. Check back every few months to see what's cookin'.
Students can display the variables as maps or lists.
They can correlate any variable with any other and display the correlations numerically or by scatterplot. And they can run up to 5-variable regressions to test these correlations for significance. Variables include measures of education, social class, health, etc.
