A music website tracked the number of new users per day over 1 week. The number of new users for each day of the 7 days was 38, 43, 45, 50, 51, 56, 67.a. What is the MAD of the number of new users per day? Round to the nearest tenth.
b. What does the value of the MAD represent? Explain
Answers
MAD = median of absolute deviations
MAD = median of the set formed by : |each value - Median|
Then, first you have to find the median of the original set
The original set is (38, 43, 45, 50, 51, 56, 67)
The median is the value of the middle (when the set is sorte). This is 50.
Now calculate the absolute deviation of each data from the median of the data.
1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17
Now arrange the asolute deviations in order
(0, 1, 5, 6, 7, 12, 17)
The median is the value of the middle: 6.
Then the MAD is 6.
Part b) MAD represents the median of the of the absolute deviations from the median of the data.

Answer: 9775 dollars
====================================
Explanation:
There are two ways to find the answer
Method 1: Take 15% of 11500 to get 0.15*11500 = 1725. This is the amount Emily pays, so she has 11500-1725 = 9775 dollars left over
Method 2: She pays 15% of her income, so she has 85% left over. This is because 100% - 15% = 85%. Now apply 85% to her income to get 0.85*11500 = 9775
