Paste a list of numbers and get the mean, median, mode, range and totals in your browser.
Mean, median and mode are the three classic measures of central tendency — three different answers to the question "what is the typical value here?". The mean adds every value and divides by how many there are. The median sorts the values and takes the one in the middle. The mode is simply the value that appears most often. They often disagree, and the disagreement is usually the most interesting part of the data.
This calculator reads your list, sorts it numerically and applies the textbook definitions. For an even number of values the median is the average of the two middle ones. The mode is the value with the highest frequency; when nothing repeats more than the rest, the tool reports "no mode" instead of inventing one, which is the mathematically correct answer. The parser understands Brazilian formatting: 3,5 is read as three and a half, and 1.234,56 as one thousand two hundred thirty-four point fifty-six.
Use it for school assignments, for average prices in a quote, for response times in a support queue or for the answers to a survey. It is also the fastest way to see when the mean is lying to you: in a list of salaries where one person earns ten times the rest, the mean is dragged upwards while the median stays close to what most people actually earn. Everything runs in JavaScript on your device — your numbers are never uploaded.
Mean = Σx ÷ n · Median = the middle value of the sorted list, or the average of the two middle values when n is even · Mode = the value with the highest frequency · Range = maximum − minimum.
Use the median when a few extreme values distort the picture, such as salaries, house prices or page-load times. The median only cares about position in the sorted list, so a single huge value cannot pull it away.
Yes. When two or more values tie for the highest frequency, the data set is bimodal or multimodal and the calculator lists all of them.
It means no value repeats more often than the others — either every number is different, or all of them appear the same number of times. In that case there is no mode to report.
No. The whole calculation happens in JavaScript on your device. Nothing is sent to a server, logged or stored, so it is safe for confidential data.
Yes. Write 3,5 or 3.5 — both are accepted, and dot-separated thousands like 1.234 are understood too. Separate the values with spaces, commas or line breaks.
