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.
When to use the median. The median is a good measure of the average value when the data include exceptionally high or low values because these have little influence on the outcome. The median is the most suitable measure of average for data classified on an ordinal scale. The median is also easy to calculate but this does not imply that it is an inferior measure to the mean â what is important is to use an appropriate measure to determine the average.
