6-2 Range, Mean, Median, and Mode

Find the range, mean, median, and mode of each data set.
Depths of Puddles (in.)
5   8    3    5      4     2    1

Start by writing the data in numerical order. 1, 2, 3, 4, 5, 5, 8
range: 8 – 1 = 7       Subtract least value from greatest value.
mean: 1 + 2 + 3 + 4 + 5 + 5 + 8 = 28        Add all values.
28 ÷ 7 = 4     Divide the sum by the number of items.
median: 4 There are an odd number of items, find the middle value.
mode: 5       5 occurs most often.

The range is 7 in.; the mean is 4 in.; the median is 4 in.; and the
mode is 5 in.
