Compute the mean of any list of numbers, plus sum, count and range.
The mean is the sum of all values divided by how many there are. The median is the middle value when sorted, the mode is the most frequent value, and the range is the difference between the largest and smallest values.
Mean
Mean = Sum of all values ÷ Count
Median
Median = middle value of the sorted list (average of the two middle values when n is even)
Range
Range = Maximum value − Minimum value
The mean averages every value and can be skewed by outliers. The median is the middle value and better represents a typical value when data is skewed.
Yes. If several values tie for the highest frequency, the data is multimodal and all of them are listed.
