Usually people are referring to the mean when asking for the average. This is found by adding up the numbers, then dividing by how many data. So there are 7 numbers (this is what to divide by). Add them up: 15 + 31 + 26 + 1 + 49 + 7 + 18 = 147 ; then 147 ÷ 7 = 21
The average is 27
Mean: 24.43 Median: 24 Mode: 31, 18
31 + 26 + 24 = 81 / 3 = 27 To find the above average, add the the three numbers together, then divide by 3
average = Sum of all terms / No. of terms = ( 31 + 29 + 26 + 27 + 32 ) / 5 = 145 / 5 = 29 therefore the average is 29!

16/18 + 15/18 = 31/18 = 1 and 13/18
4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30
26% of 31 = 26% * 31 = 0.26 * 31 = 8.06
(-25 + -70 + 15 + -31 + -25 + 40)/6 = -16
