Use this Mean Median Mode Calculator to find common measures of center from a numeric dataset. It also supports value:count input when values repeat.
Calculation Methods
Mean = sum of all values ÷ number of values
Median: Sort the data and select the middle value. If there are two middle values, average them.
Mode: The value or values that occur most often.
Example
For the dataset:
2, 4, 4, 6, 9
Mean = (2 + 4 + 4 + 6 + 9) ÷ 5 = 5
Median = 4
Mode = 4
Important Note
The mean can be strongly affected by outliers. The median is generally more resistant to extreme values, while the mode identifies the most frequently occurring value. A dataset can have more than one mode or no mode.
