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!
