For skewed data displays, the median is often a better estimate of the center of distribution than the mean because the former is unaffected by large numbers.
<h3>What is mean?</h3>
Mean refers to the average of set of two or more numbers.
Mean of a set having 'n' numbers = 
<h3>What is median?</h3>
Median refers to the middle-most value of a list of numbers, arranged either in ascending or descending order.
Median = 
Now,
- Since it takes the average of all the values in the data set, the mean is the most widely used measure of central tendency.
- Because it is unaffected by exceptionally big numbers, the median performs better than the mean when analyzing data from skewed distributions.
Hence, For skewed data displays, the median is often a better estimate of the center of distribution than the mean.
