What does the Mean, Median, Mode, Range Calculator compute?

It computes the mean (average), median (middle value), mode (most frequent value or values), and range (max minus min) for any list of numbers you enter, along with the sum, count, minimum, and maximum.

How does the calculator find the median for an even number of values?

It sorts the list and averages the two middle values. For an odd count it returns the single middle value after sorting.

Can this mean median mode calculator return more than one mode?

Yes. If two or more values tie for the highest frequency, all of them are listed as modes. If every value in the list is unique, the mode is shown as 'None'.

What separators does the number list accept?

Commas, spaces, and new lines all work, and you can mix them — for example '1, 2 3\n4' parses the same as '1,2,3,4'.

Does the range calculator handle negative numbers and decimals?

Yes. Negative numbers and decimal values are parsed correctly, and the range is simply the maximum value minus the minimum value in the list.

About Mean, Median, Mode, Range Calculator

Mean, Median, Mode, Range Calculator finds every core summary statistic for a list of numbers in one pass. Paste or type values separated by commas, spaces, or new lines and it instantly returns the mean (average), the median (middle value once sorted), every mode (the most frequent value or values), and the range (the spread between the highest and lowest value), plus the sum, count, minimum, and maximum. It correctly averages the two middle values when the list has an even count, and reports multiple modes or 'no mode' when every value is equally common. Useful for homework, grading a data set, QA sampling, or a quick sanity check on a spreadsheet column. Everything runs locally — your numbers are never uploaded.

Example

Input

1,2,2,3,4

Output

Mean 2.4 · Median 2 · Mode 2

Five values sort to 1, 2, 2, 3, 4 — the mean averages all five, the median is the middle value, and 2 is the only repeated value so it is the mode.

Common errors & troubleshooting

The results panel says to enter at least one number. — Make sure the list contains valid numbers separated by commas, spaces, or line breaks — stray letters or symbols are ignored, so an all-text entry looks empty.
Mode shows 'None' even though there are duplicate-looking values. — Check for extra decimal places or trailing spaces — 2 and 2.0 are the same number, but 2 and 2.01 are not, so near-duplicates won't count toward the mode.
Median looks off for an even-length list. — With an even count of values there is no single middle number — the Mean, Median, Mode, Range Calculator averages the two middle values after sorting, which is expected.
Mode shows more than one value. — That's correct when two or more values tie for the highest frequency — a list can be bimodal or multimodal, not just single-mode.
