Average vs. Median
The average is calculated by adding all values and dividing by the number of values. The median is the middle value after the numbers are sorted.
For example, with 10, 20, 30, 100, the average is 40, while the median is 25. This shows why an unusually large or small number can affect the average more strongly than the median.
