I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 PLEASE SEE ATTACHED IMAGE.

 First, we define the variables:
 x: number of years after 1950
 f (x): amount of vinyl sold.
 Then, with the variables defined, we have:

 68594 vinyl records were sold in 1958 ---------> f (8) = 68594

 91299 vinyl records were sold in 1961 ---------> f (11) = 91299

 38720 vinyl records were sold in 1952 ---------> f (2) = 38720

 161743 vinyl records were sold in 1967 ---------> f (17) = 161743

9,13,43,55 what is the mean absolute deviate (MAD) of their ages
lisov135 [29]

Answer:

The mean absolute deviation of this data \{9,13,43,55\} is MAD =19.

Step-by-step explanation:

The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

The steps to find the MAD include:

  1. find the mean (average)
  2. find the difference between each data value and the mean
  3. take the absolute value of each difference
  4. find the mean (average) of these differences

To find the mean absolute deviation of this data \{9,13,43,55\} you must

Step 1: Calculate the mean.

\:mean=\bar{x}= \frac{9+13+43+55}{4} =\frac{120}{4}=30

Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference .

|9-30|=21\\|13-30|=17\\|43-30|=13\\|55-30|=25

Step 3: Add the distances together.

21+17+13+25=76

Step 4: Divide the sum by the number of data points.

MAD = \frac{76}{4} =19
