About this tool
Calculate an exact decimal sum, mean, median, minimum, maximum and population or sample standard deviation for a list of numbers.
How to use
Enter one number per line or separate numbers with semicolons. Decimal points, the current language’s decimal separator and scientific notation are accepted; thousands separators are not. Copy or download the statistics.
The sum uses exact decimal arithmetic, and the mean is calculated from that sum and the count. The mean and other statistics display up to 12 significant digits. Sample standard deviation uses n−1 and needs at least two values; population deviation uses n. Limits: 10,000 values and 256 KiB input.
