The relationship between Mean and Median

The relationship between mean and mode can show you the distribution of the data. If the data is normally distributed (not skewed) the mean and the median are the same.
Median: There is an equal number of values on each side of the Median. Mean: There is an equal sum of values on either side of the mean.

If the data is rightly skewed the mode will be on the left side. That indicates that there are some extremely small numbers (outliers) in your distribution – compared to the mode, which is the most popular number.

If the data is leftly skewed the mode is on the right side. That means there are some huge outliers in your dataset – compared to the mode, which is the most popular number.

However, the median is always in the middle of the number of data values (but not necessarily of the sum of values). No matter if your data is skewed.
