Given :
Two mean absolute value deviation 15.2 and 10.9 .
To Find :
Which mean absolute value deviation represents more consistency 15.2 or 10.9 .
Solution :
First we should know what is mean absolute deviation ( M.A.D) is :
M.A.D of a data set is the average distance between each data value and the mean .
It also describe the variation in a data set .
Also , high variability means the data is spread out and low variability means that data is clustered .
So, low variation means more consistency and vice-versa .
Therefore , 10.9 M.A.D is more consistent .
Hence , this is the required solution .
1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53. N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
Let x be the total price. And you paid 75% of it which is $135.
x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.
