Frequently Asked Questions
How do I calculate the average of a list of numbers?
Enter your numbers separated by commas or on separate lines and the mean, median, mode, and other statistics appear instantly.
What is the difference between mean, median, and mode?
Mean is the sum divided by the count. Median is the middle value when sorted. Mode is the most frequently occurring value.
What if there is no mode?
If no number appears more than once, the mode shows as None. Mode only exists when at least one value repeats.
What is standard deviation?
Standard deviation measures how spread out the numbers are from the mean. A low SD means numbers cluster close to the average; a high SD means they are more spread out.
Can I paste a column of numbers from Excel?
Yes. Copy a column from Excel and paste it into the input box. Numbers on separate lines are automatically detected.
Is the average calculator free?
