CalculynHow it works
The mean is the sum divided by the count. The median is the middle value when sorted. The mode is the most frequent value. The range is the difference between the largest and smallest.
Formula
Mean = Σx ÷ n Median = middle value of sorted list
Example
For 12, 15, 18, 22, 22, 30: mean = 19.83, median = 20, mode = 22, range = 18.
