Mean, Median, Mode and Range
Mean, Median, Mode, and Range
1) Mean- is the "average” The mean is the usual average, so:
(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15
2) Median- is the "middle" value in the list of numbers.
(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13)
13 14 16 18 21
3) Mode-The mode is the number that is repeated more often than any other, so 13 is the mode.
(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13)
4) Range- the "range" is just the difference between the largest and smallest values.
The largest value in the list is 21, and the smallest is 13, so the range is 21 – 13 = 8.
(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13)
