Mean Median Mode Calculator. In statistics, mean is the average of all the data. Median is the middle value of the set of data and mode is the one that occurs most often in a set of data. The difference between the largest and smallest data is the range. This online calculator helps you to find the mean, median, range and mode of the values you entered.
