A median and mode calculator sorts your numbers to find the middle value, then counts each value to identify the most frequent one. This calculator highlights the exact middle position or pair, lists every tied mode, and shows a frequency table so you can verify both results at a glance. **Median and mode describe a data set without relying on its arithmetic average.** Paste decimal values separated by commas, spaces, semicolons, or new lines. The calculation runs locally and updates as you type, so your number set is not uploaded or stored. For an odd-sized set, the median is the single middle value after sorting. For an even-sized set, it is the average of the two middle values. A mode must occur more than once here; if several values share the highest repeated frequency, the calculator reports every one. ## How to use it 1. **Enter the data set** - Paste or type up to 2,000 numbers. Separate values with commas, spaces, semicolons, or new lines. Decimals, negative numbers, and scientific notation are accepted. 2. **Check the median positions** - Read the median card, then inspect the highlighted value or pair in the ascending list to see exactly how it was found. 3. **Review the modes** - Use the frequency table to confirm which value repeats most. Every value tied at the highest repeated count is included. 4. **Copy the summary** - Copy the median, mode, count, and complete sorted list into a worksheet, report, or note. ## Who it's for - **Students** can check homework and see which sorted positions create the median instead of receiving only an unexplained answer. - **Teachers** can demonstrate odd, even, bimodal, and no-mode examples with a frequency table that changes live. - **Researchers** can inspect the middle and most common responses in a small numeric survey or experiment data set. - **Business teams** can compare the typical sale, delivery time, rating, or order size without letting one extreme value define the center. ## Expert note A median stays stable when an outlier moves farther away, but it can still change when values are added or removed around the middle. Mode follows frequency rather than numeric size, so two distant values can both be modes. This calculator treats an all-unique set as having no mode and reports every repeated value tied for the highest count. ## Frequently asked questions ### Is my data uploaded to calculate the median and mode? No. Parsing, sorting, and frequency counting all happen in your browser. The values you enter are not sent to a calculation server or saved by this tool. Once the page is loaded, the calculator can continue working without a network connection. ### Is the median and mode calculator free? Yes. The calculator is free to use, requires no account, and has no paid result screen. You can calculate and copy results repeatedly. The only per-calculation limit is 2,000 input values, which keeps live sorting and the visual breakdown responsive. ### How do you find the median of an even number of values? Sort the values from smallest to largest, locate the two middle positions, and take their arithmetic average. For 2, 4, 7, and 9, the middle values are 4 and 7, so the median is 5.5. The calculator highlights both positions. ### Can a data set have more than one mode? Yes. A set is bimodal when two values tie for the highest repeated frequency and multimodal when more than two tie. For 1, 1, 3, 3, 8, both 1 and 3 are modes because each appears twice. The calculator lists every tied mode. ### What happens when no number repeats? The calculator reports no mode when every entered value occurs once. Although all values technically share the same frequency of one, no value occurs more often than the others, so describing the set as having no mode is the clearest convention for ordinary statistics work. ### Does the calculator accept decimals and negative numbers? Yes. It accepts signed decimals and scientific notation, including values such as -2.5, .75, and 1e3. Use a decimal point rather than a thousands separator because commas separate values. Words, currency symbols, NaN, and infinite values produce a clear input error. ### What is the difference between median and mode? The median is positional: it is the center after numerical sorting. The mode is based on frequency: it is the value or values that appear most often. Median requires ordered numeric data, while mode can also describe categories in general, though this calculator accepts numbers only. ## Related tools - [Mean, Median & Mode Calculator](https://candoya.com/tools/mean-average-calculator/) - [Standard Deviation Calculator](https://candoya.com/tools/standard-deviation-calculator/) - [Correlation Coefficient Calculator](https://candoya.com/tools/correlation-coefficient/) - [Z-Score Calculator](https://candoya.com/tools/z-score-calculator/) - [Percentage Calculator](https://candoya.com/tools/percentage-calculator/) --- *Markdown edition of , published for AI agents and other automated readers.
