Suppose we have the following test scores from two mathematics
classes:
Class 1: 85, 90, 78, 54, 88, 76, 83, 99, 49, 93, 76, 90, 78,
55, 89, 76, 65, 81, 89, 91
Class 2: 76, 80, 59, 89, 92, 68, 55, 77, 98, 95, 80, 90, 96,
80, 78, 65, 77, 92, 89, 60
What if we want to compare the two classes on the math test? We
need a way to compare the classes as a whole rather than considering individual
scores. Measures of central tendency
could help in this situation. For example, we might want to compute the mean, median, and mode of the given data.
