Answer: 5
hope this helps :)) brainliest would be appreciated!
Step-by-step explanation:
To find mean absolute deviation, the first thing to do is find the mean.
STEP 1: FIND MEAN
#1 Add all the numbers in the set:
--> 4+5+8+8+10 = 35
#2 Divide this sum by the number of numbers in the set. In this case, there are 5 numbers.
10÷5= 2
STEP 2: FIND THE DISTANCE OF EVERY NUMBER IN THE SET TO THE MEAN
4 is 2 away from the mean.
Distance: 2
5 is 3 away from the mean
Distance: 3
8 is 6 away from the mean
Distance: 6
8 is 6 away from the mean
Distance: 6
10 is 8 away from the mean
Distance: 8
STEP 3: FIND THE MEAN OF ALL THE DISTANCES
okay by now, we don't need the original set of numbers (4,5,8,8,10). Now, we're just using the distances. So our new set is:
2, 3, 6, 6, 8
To find the mean, add them all up, then divide by the number of numbers.
2+3+6+6+8= 25
There are 5 numbers, as usual.
25÷5= 5
So the median absolute deviation, (MAD), is 5.
