Scatterplot and Correlation Coefficient

This is a collection of interactive scatterplots. The simulations display the regression line and allow the usere to change the location of data points, the slope of the regression line, the correlation coefficient, and sample size, as well as it provides rollover help.

The description says that this is part of a collection. I only saw the scatterplot/correlation coefficient simulation, but I thought it was excellent, and I plan to use it in my simple linear regression lecture next semester. There is also a link to the "mirror site" which is an article about many other applets by the same author that look very interesting. I hope they're on MERLOT somewhere.

Technical Remarks:

Very quick and easy to use. Ideal for a lecture example when introducing correlation and scatterplots.
Time spent reviewing site: 10 minutes (including "mirror site."
