📈 Statistics Calculator
Paste any list of numbers — test scores, measurements, sales figures — separated by commas or spaces, and get the full descriptive summary at once: how many values, their total, the average, the middle value, the most common value, the spread and the standard deviation.
The standard deviation shown here is the population version (dividing by n), which describes exactly the data you entered rather than estimating a larger group from it.
How to use this calculator
Paste your numbers separated by commas or spaces, then press Calculate for the full descriptive summary: count, sum, mean, median, mode, range and standard deviation.
- Type or paste your numbers into the field, separated by commas or spaces.
- Double-check that every value you meant to include is there.
- Press Calculate.
- Read the seven results, from count and sum down to the standard deviation.
Frequently asked questions
What does this statistics calculator compute?
From one list of numbers it returns the count, the sum, the mean average, the median middle value, the mode most common value, the range from smallest to largest, and the standard deviation describing the spread.
Can you show a worked example?
For 2, 4, 4, 4, 5, 5, 7, 9 there are 8 values summing to 40. The mean is 5, the median is 4.5, the mode is 4, the range is 7 and the standard deviation is 2.
What if my data has no repeating value?
Then there is no mode, and the calculator says so plainly instead of inventing one. If two or more values tie for most frequent, all of them are listed.
Which standard deviation is used?
The population version, which divides by the number of values. It describes exactly the data you entered. If you are estimating a larger group from a small sample, a textbook sample version dividing by n minus 1 would run slightly higher.
