How statistics is calculated
Mean is sum/n; median is the center of the sorted values; range is max−min. Quartiles use the median-of-halves convention, excluding the overall median for odd-sized lists. For 1, 2, 2, 5, the mean is 2.5, median is 2, mode is 2, and range is 4.
Mean=Σx/n; median is the center of sorted data; range=max−min.For 1, 2, 2, 5, the mean is 2.5, median is 2, mode is 2, and range is 4.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
