Type 1 and Type 2 Errors
Description: This TED talk from February 2010 by Michael Shermer called “The pattern behind self-deception” explains Type 1 and Type 2 errors using examples of pattern recognition. It is close to 20 min, but the talk is engaging. At 3:30, he explicitly defines Type 1 and Type 2 errors. However, the rest of the talk is about how these processes are used in real life.

Standard Error of Sample Means
Description: This site allows students to calculate the standard error of the distribution of sample means.

Type 1 and Type 2 Errors
Description: This web page uses example of the U.S. justice system to illustrate the concept of Type 1 and Type 2 errors. There is also an applet that allows students to examine how these decision errors, power, alpha, and sample size influence each other.
