EXAMPLE 2.9.3
Compute the mean, median, and mode for this distribution of test scores:
92, 68, 80, 68, 84
EXAMPLE 2.9.3 SOLUTION
MEAN (arithmetic average)= (92+68+80+68+84)/5 = 392/5 = 78.4
MEDIAN (the number in the middle when all values are arranged in numerical order):
68, 68, 80, 84, 92 : 80 is the median
MODE (the number that occurs most frequently, if there is one):
68 is the mode
