2) Then, go to the web page Regression by Eye at the Rice Virtual Lab in Statistics. (To see the main page of the Rice Virtual Lab, click here.)
3) Or go to http://www.stat.uiuc.edu/~stat100/java/guess/GCApplet.html and attempt to guess the correlation coefficients.
Be prepared to ask questions about what all this means on Friday.
