Mean Median Mode Calculator

The mean is the average of all numbers (sum divided by count). The median is the middle value when numbers are arranged in order. The mode is the number that appears most frequently. For example, in the set [1, 2, 2, 3, 4]: Mean = 2.4, Median = 2, Mode = 2.

You can enter numbers in any format: comma-separated (1,2,3,4), space-separated (1 2 3 4), semicolon-separated (1;2;3;4), or mixed formats. The calculator will automatically clean and format your input.

The calculator will ignore invalid entries and only process valid numbers. It will show you which numbers were invalid and display the sanitized list of valid numbers.

Yes! If multiple numbers appear the same number of times (and more frequently than any other number), they are all considered modes. For example, in [1, 1, 2, 2, 3], both 1 and 2 are modes.

If no number appears more than once, there is no mode. The calculator will display 'No mode' in this case.

For an even number of values, the median is the average of the two middle numbers. For example, in [1, 2, 3, 4], the median is (2 + 3) ÷ 2 = 2.5.

Use the mean for normally distributed data, the median when there are outliers that could skew the mean, and the mode for categorical data or when you want to know the most common value.

Yes! The calculator supports both whole numbers and decimal numbers. Examples: 1.5, 2.75, 3.14159, etc.

Besides mean, median, and mode, the calculator also shows: count (number of values), sum, minimum value, maximum value, and range (max - min).

There's no strict limit, but for best performance, we recommend entering up to 10,000 numbers. The calculator can handle large datasets efficiently.
