FAQ
How do I calculate the average (mean)?
Add up all the numbers and divide by the count. Paste your numbers and the mean is computed instantly, with median, mode and more. Separate with commas, spaces or new lines.
Mean vs median vs mode?
Mean is sum ÷ count (the everyday average); median is the middle value when sorted (robust to outliers); mode is the most frequent value. All three are shown.
What is standard deviation?
It measures how spread out the numbers are from the mean — small means tightly clustered, large means widely varied. Both population and sample values are shown.
What separators can I use?
Commas, spaces, tabs or new lines — paste straight from a spreadsheet column. Non-numeric junk is ignored.
