- The mean = average = sum of all data points / number of values.
- Median is the middle value of an ordered data set.
Mean of the monthly sales:
Mean = (8 + 5 + 8 + 10 + 5 + 6 + 11 + 9 + 8 + 5 + 9 + 6)/12
Mean = 7.5
Median of the monthly sales:
5, 5, 5, 6, 6, (8, 8,) 8, 9, 9, 10, 11
Median = (8 + 8)/2
Median = 8
