The purpose of our modeling effort is to predict future outcomes. We assume the data collected are both accurate and relatively precise. For our oscillating data, we examined several mathematical modeling forms for predictions. We also examined both ignoring the oscillations as an important feature and including the oscillations as an important…

Describes a menu-driven, data plotting program which runs on any Apple II plus, IIE, or IIC microcomputer. The program does a least-squares analysis of the data and gives the user the option of fitting the line through the data points. The complete Applesoft program listing is included. (JN)

Investigates using computer spreadsheets in math classes. Describes current spreadsheets on the market. Summarizes how the spreadsheets work and provides information to build a template to find function maximums and minimums. Lists step by step instructions. (MVL)

Applies microcomputer technology to the development of a data acquisition and analysis system for the study of measuring the human lung capacity and metabolism. Discusses the chain-compensated spirometer, interfacing hardware, data acquisition hardware and software, and the applicability of the system to other biological measurements. (MDH)
