Answer:
The mean absolute deviation (MAD) of this data set is 2.4
Step-by-step explanation:
step 1
Find the mean
To find out the mean sum all values and divide by the number of values in the data set
we have the set of data
The number of values is 10
so
The mean is equal to
step 2
Find out the absolute value of the difference of each value from that mean
so
we have
step 3
we know that
The Mean Absolute Deviation (MAD) is the mean of those distances
therefore
The mean absolute deviation (MAD) of this data set is 2.4
