Time Comparison of Practical Mathematical Calculations Using Customary and Metric Systems.
Tew, E. James, Jr.
The purpose of this practicum was to determine if adult students engaged in training for high technology jobs can realize a time savings if customary or metric units of measure are used for practical mathematical calculations. Two quizzes were developed, and validated, using customary and metric units for the same type of problem, and the time to solve each problem was recorded. The objective was to determine if there was a significant difference in time per correct answer for either unit of measure. Both quizzes, each having both units of measure for different types of problems, were give to 20 industrial adult students without prior notification. Provided with each quiz was an instruction sheet regarding the procedures to be followed and method of recording time. The recommendation resulting from this study is that practical mathematical calculations be performed using metric units of measure to the extent permitted by limiting variables including measuring and test equipment, specifications, and blueprints which have not been converted to metric units. The paper includes an introduction to the problem, its background and significance, and procedures for the study, data resulting from the study, and conclusions. Copies of the quizzes and the statistical calculations are appended. (KR)
