This resource presents a complete and detailed look at linear regression. This guide provides lots of details and graphs to explain each concept.

Students will use this computer applet to simulate water running out of a tube. By varying the tube diameter and noting time changes and the height of the water in the tube students will create a formula to fit the curves of height...

Definitions of the basic concepts in statistics. Great for review and discussion or for introduction into topics.

Students are introduced to logistic growth curves using a graphing calculator. Lab data includes the number of bacteria over a 20-hour period. The activity numerically approximates the derivative and uses regression to find a curve...

A program that will randomly generate data the students can then graph and curve fit. Gives students a chance to learn Logger Pro or other graphing program before starting actual labs.

This program was designed to make sure students can properly curve fit the different types of data they will run across in class.

This page goes over what regression method is and how a regression line fits in. Dr. MAth also suggests a book on regression if you are interested.

Based off of the hit television show NUMB3RS, this lesson introduces students to the chi-squared statistical analysis. Although not completely in depth, the lesson does expose students to degrees of freedom, a simple chi-squared formula,...

Dozens of statistical terms are defined and illustrated in this glossary.

Explains what interpolation and extrapolation are and methods used for them in statistics. Gives real-world examples of their applications in telecommunications, engineering, thermodynamics etc.

Many measurements fit a special distribution called the normal distribution.

Change the standard deviation of an automatically generated normal distribution to create a new histogram. Observe how well the histogram fits the curve, and how areas under the curve correspond to the number of trials.
