About Statistics Calculator — Mean, Median, Mode
This statistics calculator turns a raw list of numbers into a full descriptive-statistics summary. Paste values separated by commas, spaces, or one per line and instantly see the count, sum, mean, median, mode, minimum, maximum, range, variance, standard deviation, and quartiles — everything you need to understand the shape of a dataset at a glance.
It reports both the sample standard deviation (n−1 divisor) and the population standard deviation (n divisor), so you can use the right one for your data without second-guessing the formula. Mode handles multi-modal sets, returning every value tied for the most frequent.
Like the rest of these tools, the mean median mode calculator runs entirely in your browser. Your numbers are never uploaded, which makes it safe for analysing private or sensitive data offline.
Features
- Count, sum, mean, median, mode, min, max, and range in one pass
- Both sample (n−1) and population (n) variance and standard deviation
- Quartiles (Q1, Q3) and multi-modal mode detection
- Accepts commas, spaces, or newlines as separators; works fully offline
How to use
- Paste or type your numbers into the input — one per line or comma-separated.
- Read the aligned breakdown of every statistic in the output pane.
- Use the sample standard deviation for a sample, or the population value for a full dataset.
- Copy any result, or clear the input and start again.
Frequently asked questions
What is the difference between sample and population standard deviation?
Population standard deviation divides by n and is used when your numbers are the entire dataset. Sample standard deviation divides by n−1 (Bessel’s correction) and is used when the numbers are a sample drawn from a larger population. This tool shows both so you can pick the right one.
How is the median calculated?
The values are sorted, then the median is the middle value. For an even count there is no single middle, so the median is the average of the two central values.
What happens when there is more than one mode?
The mode is the most frequent value. When several values are tied for the highest frequency the dataset is multi-modal, and all of them are returned. If every value appears once there is no mode.
How are the quartiles computed?
Q2 is the median. Q1 and Q3 are the medians of the lower and upper halves of the sorted data, splitting around the median (the exclusive method). They mark the 25th and 75th percentiles.
Does my data get sent anywhere?
No. Every calculation runs locally in your browser using plain arithmetic. Your numbers never leave your device, so it is safe for private or sensitive data.
