Question

The following data points represent the number of alligators in each body of water near Tom's house. quad 8, 5 , 12, 15, Find the mean absolute deviation (MAD) of the data set. alligators

Answer 1

Step-by-step explanation: answer 7

Answer 2

`3.5` - written in
`2/14/2021`

Explanation:

#1st Step: First, let's find the mean:
`(8+5+12+15)/(4)=(40)/(4) =10`

#2nd Step: Next, let's find the distance each data point is from the mean:

Data Point | Distance from the mean

`8` |
`10-8=2`

`5` |
`10-5=5`

`12` |
`12-10=2`

`15` |
`15-10=5`

#3rd Step: The mean absolute deviation (MAD) is the mean of the distances from the mean:
`(2+5+2+5)/(4) =(14)/(4) =3.5` alligators

So this is how I found the answer,
`3.5`. (Happy Valentines Day!)
