Answer: Median is the best measure of central tendency best represents the data.
Value of median= 15
Step-by-step explanation:
The given data : $10, $20, $15, $100, $10, $15, $10.
We observe that the above data has an outlier in it .
$100 is an extremely large value as compare to the other values in the data.
It means the data contains outlier.
Commonly , mean is the best measure of the central tendency.
We know that , when there is an outlier in the data , we prefer Median over Mean to measure the central tenancy of the data.
So for the given data set ,
Median is the best measure of central tendency best represents the data.
To find median , first arrange data in an order , we get
10 , 10 , 10 , 15 , 15 , 20 , 100
Number of data values = 7 (odd)
So Median= Middle-most number= 15
Hence, the median of data = 15
or abot 0.6
