Dear All On my www-page I have a Flash applet where you can make your own scatterplot and you get the regression model and the correlation coefficient
http://noppa5.pc.helsinki.fi/koe/flash/corr/cp18.html One day I got some positive feedback: >Hello, >My name is ------ and I am 10 years old. I was visiting your statistics >website and found the section that allows you to create a scatter plot >and calculate a correlation coefficient. It was a lot of fun, and I wanted >to try to use it for my science project this year. > .... > Do I understand the message correctly, if I say " It is difficult to calculate the correlation coefficient, but easy to make a scatterplot. If I can get the correlation coefficient just by clicking the data into the scatterplot, I am happy." Do you think, that this is a better way to teach correlation than give them the data, formula and some statistical package.
