Mean is the average of a set of data points = (Sum of all data) / Quantity of DataMedian is the middle of a set of data points = Data whose index is the integer nearest ((Number of Data+1) / 2)Example Data:2, 3, 5, 3, 2The mean = (2+3+5+3+2)/5 = 15/5 = 3The median = Index((5+1)/2) = Index(6/2) = Index(3). The third item on our list is 5.
