The mean is the point on which a distribution would balance, the median is the value that minimizes the sum of absolute deviations, and the mean is the value that minimizes the sum of the squared deviations.
A definition that is key. A mean is about balance. Median is making it mini.
The mode is the most frequently occurring value in the dataset.
Paying close attention and realizing the mode would oftentimes be seen.
If they are based on a small number of observations, it can be misleading to label the pie slices with percentages.
