About These Statistics
Median
The median is the middle value after sorting. It stays more stable when your data includes extreme highs or lows.
Mode
The mode is the most frequent value. A dataset can have no mode, one mode, or multiple equally frequent modes.
Range & Standard Deviation
Range measures total spread (max minus min). Standard deviation measures typical distance from the mean.
