Thank you for taking the time to go through this lesson. I hope it helped you not only understand, but enjoy statistics.
For further experience with variance, I recommend you check out Ed Malczewski's lesson on variance and covariance (you'll probably recognize some of the materials).
I hope you will take the time to send me an email (at Jay Hill) with your comments and criticisms. I would love to hear from you and I'm always looking to improve my lessons.
Thanks again and I hope you continue to surf the net for knowledge.
