Find the mean and the mad. [note: type your answers as decimal numbers, rounded to the nearest tenth.]

135, 160, 145, 155, 170, 150, 142

mean :

mad(mean absolute deviation):

Part 1) The mean is 151

Part 2) The mean absolute deviation (MAD) is 9.1

Step-by-step explanation:

we have

set of data

step 1

Find the mean

Sum all the values and divide by the number of values

step 2

 Determine the  absolute value of subtract the mean from each value

step 3

Find the mean of those distances

----> this number is called the mean absolute deviation (MAD)

i had a similar work too, kindly contact professor james. so far he has handled 2 online tests and a paper for me. i attained 100% in both tests and 97% on the paper. kindly let him know that i referred you, i’m johnson.
