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.
The median is the middle value in distribution when the values are arranged in ascending or descending order. The median divides the distribution in half (there are 50% of observations on either side of the median value). In a distribution with an odd number of observations, the median value is the middle value. 54, 54, 54, 55, 56, 57, 57, 58, 58, 60, 60. When the distribution has an even number of observations, the median value is the mean of the two middle values.
