(11 + 16 + 15) ÷ 3 = 14 is the average
Get real, same as 3 x 15...
14 + 15 + 16
16, 12+15+21 = 48/3 = 16
Add numbers then divide total by amount of numbers So 14 16 has mid number of 15 as (14+16)/2 = 30/2 = 15 (as there are 2 numbers of 14 and 16) or 6 12 24 has mid number of 14 as (6+12+24)/3 = 42/3 = 14 (as there are 3 numbers of 6 and 12 and 24) and so on
(16+15+14)/3 = 15
(11 + 16 + 15) ÷ 3 = 14 is the average
9 15 15 15 16 (five data) Range = 16 - 9 = 7 Mean = (9 + 15 + 15 + 15 + 16)/5 = 70/5 = 14 So we have: (9 - 14)2 = (-5)2 = 25 (the square of the difference of data value and the mean value) (15 - 14)2 = 12 = 1, 3(1) = 3 (16 - 14)2 = 22 = 4, the sum is 32 The standard deviation = √(32/5) ≈ 2.5

14 + 15 + 16
16, 12+15+21 = 48/3 = 16
Average can be solved by adding all of the numbers and dividing by the total number of items being added. So:14 + 15 + 16 = 45 / 3 numbers = 15
Add numbers then divide total by amount of numbers So 14 16 has mid number of 15 as (14+16)/2 = 30/2 = 15 (as there are 2 numbers of 14 and 16) or 6 12 24 has mid number of 14 as (6+12+24)/3 = 42/3 = 14 (as there are 3 numbers of 6 and 12 and 24) and so on
-15
since there are zeros the total amount of data given is different. for example: 14+16=30 30/2= 15 with zeros: 14+16+0=30 30/3=10
16/3 = 80/15 18/5 = 54/15 80 + 54 = 134/15 = 8 and 14/15
14/15 + 3/5 = 14/15 + 9/15 = 23/1514/15 + 3/5 = 14/15 + 9/15 = 23/1514/15 + 3/5 = 14/15 + 9/15 = 23/1514/15 + 3/5 = 14/15 + 9/15 = 23/15
