http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1971
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1971September 22, 2009 Activity Webinar presented by Diane Evans, Rose-Hulman Institute of Technology and hosted by Leigh Slauson, Capital University. This webinar is based on an activity found at www.lhs.logan.k12.ut.us/~jsmart/tank.htm and other on-line resources (see references). During World War II, the British and U.S. statisticians used estimation methods to deduce the productivity of Germany's armament factories using serial numbers found on captured equipment, such as tanks. The tanks were numbered in a manner similar to 1, 2, 3, ..., N, and the goal of the allies was to estimate the population maximum N from their collected sample of serial numbers. The purpose of this activity is to introduce students to the concept of an unbiased estimator of a population parameter. Students develop several estimators for the parameter N and compare them by running simulations in Minitab.

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1934
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1934July 28, 2009 Activity webinar presented by Jo Hardin, Pomona College, and hosted by Leigh Slauson, Otterbein College. Based on an activity by John Spurrier, this webinar uses a baseball example to introduce students to Bayesian estimation. Students use prior information to determine prior distributions which lead to different estimators of the probability of a hit in baseball. The webinar also compares different Bayesian estimators and different frequentist estimators using bias, variability, and mean squared error. The effect that sample size and dispersion of the prior distribution have on the estimator is then illustrated by the activity.Sun, 2 Aug 2009 10:42:47 -0400Cartoon: Entering Chicago

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1717
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1717This classroom example illustrates the concept that estimators are random variables. The example makes use of the classic problem of estimating the size of a population by observing serial numbers, specifically estimating the number of taxis in a city. In this article from the Journal "Teaching Statistics," The author explains how to encourage a discussion among students about the best estimator for a population size. The author then uses a simulation to determine which of a group of candidate estimates should be used.Wed, 7 Mar 2007 06:56:13 -0500Quote: Hawking on precision
