Median and Mode Calculator
Find the median and mode of any number set.
How to use
- 1 Type or paste your numbers, separated by commas, spaces or new lines.
- 2 The list is parsed and sorted automatically.
- 3 Read the median and the mode (or modes) in the result card.
- 4 Check the sorted list to confirm the values were read correctly.
- 5 Copy the result for your notes or report.
About Median and Mode Calculator
The Median and Mode Calculator finds the two "middle" measures of central tendency for any list of numbers you paste in.
The median is the value that sits in the middle once the numbers are sorted — and when the list has an even number of entries, it is the average of the two central values, so the answer stays meaningful for any sample size.
The mode is the value that appears most often, which is especially useful for categorical or repeated data where the average can be misleading.
Just type or paste your numbers separated by commas, spaces or new lines; the tool parses them, sorts them and reports the median, the mode (or modes), and the sorted list for quick checking.
It handles the tricky cases properly: multimodal data, where two or more values tie for most frequent, shows every mode; a set where every number occurs equally often is correctly reported as having no mode rather than guessing one; and a single repeated value is treated as the mode.
Calculations run entirely in your browser with plain JavaScript, so your data is never uploaded, logged or stored, and the page keeps working offline.
It is a fast, private companion to mean and standard-deviation tools for everyday statistics, homework and data sanity checks.
FAQ
What happens when there is more than one mode?
If two or more values tie for the highest frequency, the data is multimodal and every tied value is listed as a mode, along with how many times it appears.
What if no value repeats?
When every number occurs the same number of times — for example all values are unique — there is no single most frequent value, so the tool reports that the set has no mode.
How is the median found for an even number of values?
The numbers are sorted and the median is the average of the two middle values, which keeps the result accurate for even-length lists.
