Description: This application is designed to enhance your understanding of standard scores, areas under the normal curve, and probability as applied to inferential statisitics. With this application you can: scale the normal curve according to specific means and standard deviations; change any of the values in the z-score formula and see the resulting changes depicted on the normal curve; specify an exact amount of area under the curve and then see the corresponding standard- and raw-score values; and return exact areas between two raw- or standard-score values.
