• ### GAISE Draft Report

The GAISE project was funded by a Strategic Initiative Grant from ASA in 2003 to develop ASA-endorsed guidelines for assessment and instruction in statistics in the K-12 curriculum and for the introductory college statistics course.
• ### Full Factorial Example (Engineering Statistics Handbook)

This section in the Engineering Statistics Handbook takes a data set and walks the user through analysis and experimental design based on the data.
• ### What Are The Odds?

This website provides lesson plans, activities, a problem bank, and links to references that meet NCTM standards for probability.
• ### ** Binomial Distribution

This JAVA applet is designed to give students practice in calculating basic probabilities using the binomial distribution. The applet gives students short problem descriptions that require a binomial probability to solve. The user is then prompted to follow a step by step process to find the probability. Users must answer a step correctly before the applet will allow them to move on to the next step. The page also gives further exercises that allow the user to think about binomial distributions more deeply and gives a link to a more detailed information about the binomial distribution.

• ### Student's T Distribution

The larger the degrees of freedom, the closer the t-density is to the normal density. This reflects the fact that the standard deviation s approaches for large sample size n. You can visualize this in the given applet by moving the sliders.
• ### Building a Probability Tree Applet

This applet simulates a probability tree diagram. Step 1: Click inside the appropriate box on the desired level to build the tree. Step 2: Click on "Set Probabilities" at the top. Step 3. When you enter the respective probabilities, you must hit the ENTER key after each one. Step 4: Once all of the probabilities have been set (they should be blue), click "Final Tree" Step 5: Click "Simulation".
• ### Regression/Correlation

The ninth chapter of an online Introduction to Biostatistics course. Lecture notes and links for futher reading are provided.
• ### Comparing Two Groups

This page discusses the procedures and applications of the two sample t test and the paired t test.
• ### Variance and standard deviation

This source defines and explains variance and standard deviation.
