Games / Demonstrations

Correlation
     Game:  Can you guess the correlation?
     Game:  Can you get on the top 20 list?
 
Descriptive Statistics
Live data from Old Faithful eruptions displayed in an interactive histogram that allows one to change bin widths

Why use n-1 as a divisor when finding variance instead of n?  This applet demonstrates why "s" is an unbiased estimator of "sigma." 

General sets of applets
     Cut-the-knot applets for all areas of mathematics and statistics
     Duke University applets
     Rossman/Chance applets
     R. Webster West applets

Inference
Classifying Statistics Problems - how does a student determine which test to use? This interactive site poses problems and asks students to determine the appropriate test to use.  If he or she guesses incorrectly initially, the applet provides hints in order to proceed.
Confidence Intervals - an interactive exercise to explore what it means to be 95% confident
You Tube video on the meaning of p-value as explained through a study of nuts found in Chocco Nutties.
Power - WISE (Web Interface for Statistics Education from Claremont Graduate University) has many wonderful applets.  Scroll down on the left to "statistical power" and experiment with changing n, the confidence level, the population parameter, etc.
Type I and Type II errors explained in the context of the criminal justice system
Visual demonstration of Type I, Type II errors and power that provides interactive sliders from Clemson University.
You Tube video debate on whether or not to take action against Global Warming analyzed in terms of Type I and Type II errors.

Probability
Monty Hall dilema
Game:  Let's Make a Deal - play Monty Hall's game to see whether one should switch or not.
Discussion of the problem - why is it best to always play the game the same way?
An example of Simpson's Paradox based on a longitudinal study of the growth of children in South Africa

Surprising Problems explored through applets, such as the birthday problem, the coupon problem, matching problems, a tree problem.  These were created by Susan Holmes with support of the NSF.

Regression
     GSP demonstration of LSRL
     Can you identify an outlier?
     Can you eyeball a line to minimize the SSE?

Sampling Distributions - an interactive tool that enables students to practice this concept
