Find the median, mode, and range of the data in the stem-and-leaf plot below.
Stem Leaves
1 112
369999
222577
4 022

The median is 31.5

The mode is 39

The range is 31

Step-by-step explanation:

The median is the middle number of arranged data from small to big in a set of data

The mode is the most repeated number in a set of data

The range is the difference between the greatest and the smallest numbers in a set of data

The data from stem-and-leaf plot are

11, 11, 12, 22, 22, 25, 27, 27, 36, 39, 39, 39, 39, 40, 42, 42

∵ There are 16 data

- There is no one middle number because the number of the

    data is even, so the median will be the average of the

     two middle numbers

∵ 16 ÷ 2 = 8

∴ The middle numbers are the 8th and the 9th numbers because

   there are 7 numbers before them and seven numbers after them

∵ The 8th number = 27

∵ The 9th number = 36

∴ The median =

∴ The median = 31.5

∵ The mode is the most repeated number

∵ 39 is repeated 5 times and no other number repeated more

   than 5 times

∴ The mode is 39

∵ The range = Greatest number - Smallest number

∵ The greatest number is 42

∵ The smallest number is 11

∴ The range = 42 - 11

∴ The range = 31
