Hi Class,

Which is the best measure of central tendency depends on the shape/distribution of the data.  When data is skewed, a mean is probably not a good measure.  For example, if we have a data like this 1,  100, 100, 100,100, 101,101,101.  What would be the mean and the median, which one do you think is a better measure of central tendency?  Below are the answers:

Mean=(1+100+100+100+100+101+101+101)/8=88

Median=100

 

As we see the value “1” skewed data.  In this data set, median is a better measure to represent the central tendency.

 

Please chime in your thought!
