Question
What can we say about the distribution when the mean and median are different?
Solution
When the mean and median of a distribution are different, it suggests that the distribution is not symmetrical. This is often an indication of skewness in the distribution.
-
If the mean is greater than the median, the distribution is said to be positively skewed. This means that there are a number of data points with values greater than the mean, pulling the mean value higher.
-
If the mean is less than the median, the distribution is negatively skewed. This means that there are a number of data points with values less than the mean, pulling the mean value lower.
-
The greater the difference between the mean and median, the higher the skewness.
-
In a perfectly symmetrical distribution, the mean and median would be the same.
-
However, it's important to note that having a different mean and median is not enough to determine the shape of the distribution. Other factors such as kurtosis and the range of data should also be considered.
