Mean = all numbers added up ÷ amount of numbers
So 22 + 24 + 26 + 20 + 29 + 28 + 26 = 175
175 ÷ 7 = 25 for mean
Median = middle number when arranged in order
20, 22, 24, 26, 26, 28, 29.
Middle number is 26.
Mode = most frequent number
Also 26 because it appears twice whereas all the other numbers only appear once.
Range = highest number - lowest number
29 - 20 = 9.
