Mean, median & mode
Paste a list of numbers separated by commas, spaces, or line breaks: get the mean, median, mode, minimum, maximum, sum, and count in one click.
Separate values with commas, spaces, semicolons, or line breaks. Use a period for decimals (e.g. 7.5).
Mean, median, or mode: which one should you use?
The mean is the sum of the values divided by how many there are — great for "well-behaved" data, but very sensitive to outliers: a single extreme number can pull it far off. The median is the middle value of the sorted list and stays stable even with anomalies, which is why it's the standard for salaries and home prices. The mode is the value that appears most often, and it's the only one of the three that also makes sense for non-numeric data, like colors or shirt sizes.
How edge cases are handled
If no value repeats, there is no mode and the tool tells you so; if several values tie for the highest frequency, the distribution is multimodal and all of them are shown. With an even number of values, the median is the average of the two middle ones.
You can freely mix separators (commas, spaces, line breaks): any non-numeric entries are skipped and flagged below the result so you can fix them on the spot. Negative numbers are accepted too.
