A BASIC Microcomputer Program for Estimating Test Reliability.

PDF pending restoration

Cobern, William W. – 1986

This computer program, written in BASIC, performs three different calculations of test reliability: (1) the Kuder-Richardson method; (2); the "common split-half" method; and (3) the Rulon-Guttman split-half method. The program reads sequential access data files for microcomputers that have been set up by statistical packages such as…

Technology, Linear Equations, and Buying a Car.

Peer reviewed

Sandefur, James T. – Mathematics Teacher, 1992

Discusses the use of technology in solving compound interest-rate problems that can be modeled by linear relationships. Uses a graphing calculator to solve the specific problem of determining the amount of money that can be borrowed to buy a car for a given monthly payment and interest rate. (MDH)
