Mean can be found by adding up all of the numbers and then dividing that by a number of numbers.
2 + 3 = 5
5 + 5 = 10
10 + 8 = 18
18 + 8 = 26
26 + 0 = 26
26 + 2 = 28
So our outcome is 28. Since we have 7 numbers in the stem and leaf plot we have to divide 28 by 7.
28 ÷ 7 = 4
So your answer is 4!
Hope this helped. Have a great day!
