The formula this calculator uses
Mean Median Mode Calculator
Mean = sum of values ÷ count
Median = middle value after sorting
Mode = value(s) that appear most often
Example: 5, 8, 12, 8, 7, 10, 8 → Mean ≈ 8.286, Median = 8, Mode = 8
Choosing the right average
Mean, median, and mode each answer a different question about a data set. Use mean for symmetric distributions, median when outliers are present, and mode for categorical or discrete data where the most common value matters.

Frequently asked questions
What is the difference between mean and median?
Mean is the arithmetic average; median is the middle value and is less affected by extreme outliers.
Can there be more than one mode?
Yes. A data set can be bimodal or multimodal when several values share the highest frequency.
What if every number appears once?
There is no mode (or every value is a mode, depending on definition). This tool reports “No mode”.
Should I use mean or median for salaries?
Median is usually preferred for income data because a few very high salaries can pull the mean upward.
