Book Description
The study compared the efficiency of decimal and sexagesimal, or normal, time systems in the solution of addition problems, using the time required to reach a solution and the number of errors as dependent variables. Twelve subjects solved sets of addition problems composed of 8, 16, or 24 digits, using the decimal and sexagesimal time systems. When the conversion process required by the sexagesimal system was included in the analysis, the results clearly showed that addition using the sexagesimal system required significantly more time (1 1/2 to 2 1/2 times as much) and produced significantly more errors (1 1/2 to 3 times as many). When the conversion process required by the sexagesimal system was excluded from the analysis, there was no significant difference between the two time systems on either dependent variable. (Author).
