Handles the awkward cases
Multimodal data lists every mode. Data where nothing repeats reports no mode rather than a wrong one.

Any separator works: spaces, commas, semicolons, tabs, or one value per line.

Read the three measures
Mean leads, with median and mode below it. Multiple modes are listed; if every value is unique you get no mode.

Compare them
A mean well above the median usually means a few large values are pulling it up.
Why all three at once
The mean, median, and mode agree on symmetric data and disagree on skewed data. Seeing the gap is the point.
Even and odd counts
The median averages the two middle values when the count is even, which is the standard definition.
Spread included
Count, range, and standard deviation come along so you are not looking at center in isolation.
Where these show up
Survey ratings
Median is often the honest headline when a handful of extreme ratings skew the mean.
Salary and price data
Median is the standard summary for income and house prices precisely because the mean is skewed.
Homework and stats classes
Check all three measures of central tendency in one pass.
The three measures
Mean = Σx ÷ n · Median = middle value when sorted · Mode = most frequent value
With an even count, the median is the average of the two middle values. A dataset can have several modes, or none at all if no value repeats.
Mean vs median
Mean
- Uses every value
- Moved a lot by outliers
- Right for symmetric data
- Feeds into standard deviation and t-tests
Median
- Uses only the middle position
- Barely moved by outliers
- Right for skewed data
- Standard for income and price summaries

Frequently asked questions
What is the difference between mean, median, and mode?
Mean is the arithmetic average: add everything and divide by the count.
Median is the middle value once the list is sorted.
Mode is the value that appears most often. A list can have more than one mode, or none.
When should I use the median instead of the mean?
When the data is skewed or has outliers. Incomes, house prices, response times, and support ticket durations all have long tails, so the mean sits above what a typical case looks like.
A good rule: if the mean and median differ noticeably, quote the median and say why.
What if there is no mode?
If every value appears exactly once there is no mode, and this calculator says so rather than inventing one. That is common with continuous measurements like weights or times.
Can there be more than one mode?
Yes. Two values tied for most frequent makes the data bimodal, and more than two makes it multimodal. This tool lists all of them.
A bimodal survey result often means two distinct groups are answering differently, which is worth splitting out.
How do you find the median of an even number of values?
Sort the list and average the two middle values. With eight numbers, that is the average of the fourth and fifth.
Can I weight the values?
Not here. Use the weighted average calculator when some values should count more than others, for example pooling group scores by sample size.
Is my data uploaded?
