Teacher Answer Sheet

Mean, Median, Mode & Range

Answers are listed in question order. The mean is found by adding all the values and dividing by the number of values. The range is the largest value minus the smallest value.

Sum: 35; 35 ÷ 5 = 7
Mean: 7    Median: 6    Mode: 6    Range: 11 − 4 = 7

Sum: 90; 90 ÷ 5 = 18
Mean: 18    Median: 18    Mode: No mode    Range: 24 − 12 = 12

Sum: 48; 48 ÷ 6 = 8; median = (6 + 8) ÷ 2 = 7
Mean: 8    Median: 7    Mode: 6    Range: 14 − 4 = 10

Sum: 42; 42 ÷ 7 = 6
Mean: 6    Median: 4    Mode: 4    Range: 12 − 2 = 10

Sum: 175; 175 ÷ 5 = 35
Mean: 35    Median: 35    Mode: No mode    Range: 45 − 25 = 20

Sum: 96; 96 ÷ 8 = 12; median = (10 + 12) ÷ 2 = 11
Mean: 12    Median: 11    Mode: 10    Range: 20 − 6 = 14
