Angela collected the data displayed in the table below. -8,6.2,2.5,12,-2,-1.3,15,-2,0,7
What is the mean absolute deviation for this set of data?
A 2.94
B 1.25
C 4.59
D 5.688

A

2.94

Step-by-step explanation:

add all the numbers together -8+6.2+2.5+12+-2+-1.3+15+-2+0+7=29.4.

next you divide 29.4 by how much numbers there are in the equation which in this case its 10.

29.4/10=2.94

so its A :)

The answer is 2.92

Step-by-step explanation:

All u have to find the mean is add all of the numbers up then divide that by how many numbers their are. Example: -8+6.2+2.5+12+-2+-1.3+15+-2+0+7. Their are 10 numbers in this equation so just add those numbers up and divide by how many numbers their are. Hope this helped :)
