University of Utah: Java Area Applet

The Applet illustrates how to use the old-fashioned tables of normal probabilities and areas under the normal distribution cureve to arrive at corresponding graphs of the areas. A good resource for the topic.

The Applet assists the user in questions which specify a probability and ask for the relevant range of raw scores or z scores. The program will also transform from raw to z scores and back again, if needed.

Use this site to learn the basics about rational numbers in this tutorial. There are exercises to check for understanding are included.

This Applet allows the user to grab and drag the ends of the included region below the standard normal curve to the appropriate places needed. The user directly experiences the connection between the shaded area under the curve and the...

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Contains information about the life and works of Archimedes. Includes a Pi applet. Has links to Eratosthenes of Cyrene, A listing of Pi to 10,000 digits, a biography of Archimedes, notes on Pi, and sources on Archimedes' screw.

This Applet will assist the user in questions which specify a range of raw scores or z-scores and ask for a probability associated with them.

[Free Registration/Login Required] This is a formative assessment task where students are asked to estimate the population of Utah based on information given about its population density and the perimeter of its state boundaries. Samples...

The history of the normal curve and its use in statistics is presented. An Applet is provided for the user to adjust the left and right edges of the probability and see the effect on the area under the curve.

You can have a good time with this java applet that lets you place adjustable shapes under a curve and then sums the areas to approximate the area of the curve.
