Describe a real-life situation where the mean is not a good indicator of central tendency.

Solution

In situations where there are outliers is the mean a bad indicator of central tendancy.

Take this following example:

Take the case of marks in class.

Take this case in particular - There are just 5 people with 98+marks out of 100. The next highest is 88 and other numbers are significantly below 88. The mean is 80 lets suppose and the median is 65. What thus this show?

This shows that because there are outliers in the series ( above 98 values) this data is skewing the mean. The mean gets disproportionately high to 80, although the median is 65.
