Question

71, 92, 94, 93, 98, 85, 66, 70, 68, 93, 87, 71, 85, 52, 61, 62, 85, 69, 95, 79

Calculate the mean for the data list above.
ОА. 82
ОВ. 78.8
Ос. 93
Op. 87

Answer 1

To find the mean you must add all the numbers together then divide the sum by the total amount of numbers in the data set

71 + 92 + 94 + 93 + 98 + 85 + 66 + 70 + 68 + 93 + 87 + 71 + 85 + 52 + 61 + 62 + 85 + 69 + 95 + 79 = 1576

There are at total of 20 numbers in this data set so you must divide 1576 by 20

1576 / 20 = 78.8

Hope this helped!
