Question

Determine measurements of data for the following numbers:

78, 95, 77, 92, 87, 79, 94, 86, 88, 94
Mean:
Median:
Range:
Mean absolute deviation:

Answer 1

Answer: mean=87, median=87.5 and range=18

Explanation:

Mean:

First add all the numbers

78+95+77+92+87+79+94+86+88+94 = 870

Then you divide the answer by counting the numbers

870÷10

=87

Median:

First arrange the numbers in ascending order (from smallest to largest)

77, 78, 79, 86, 87, 88, 92, 94, 94, 95

pick the two middle numbers which is 87 and 88

then you do
`(87+88)/(2)`

= 175÷2

= 87.5

range = Largest number - smallest number

= 95-77

= 18
