Math Calculators
Average Calculator
Calculate the mean, median, and mode of a set.
Enter the values and review the result.
Enter a list of numbers separated by commas.
Calculation assumptions
- *Mean is calculated as the sum of all values divided by the count.
- *Median is the middle value after sorting the numbers.
- *Averages can hide spread or outliers, so compare mean and median when values vary widely.
Enter your values and press Calculate.

Mean vs. Median
The mean is the sum of all numbers divided by the count. The median is the middle value after the numbers are sorted.
Example: for 10, 20, 30, 40, and 50, the sum is 150 and the count is 5. The mean is 150 / 5 = 30, and the median is also 30.
Common mistakes
- Do not ignore outliers; one very large or small number can move the mean a lot.
- Use commas between values so each number is parsed separately.
- Compare mean and median when data is uneven.
- Remember that average alone does not show spread or consistency.

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Results depend on the values you enter and any simplified assumptions used by the tool. Verify important results before making decisions or submitting official information.

Frequently Asked Questions
Common questions about Average Calculator and how to read the result.
Can I use decimals?
Yes, the calculator supports both whole numbers and decimals.
What is the mean formula?
Mean = sum of values / number of values.
What is the median?
The median is the middle value after sorting the list. For an even count, it is the average of the two middle values.
Why are mean and median different?
They can differ when the data has outliers or uneven spread.
Can I enter negative numbers?
Yes. Negative numbers and decimals are accepted as long as they are valid numeric entries.
Does average show variation?
No. Average summarizes the center, but it does not show how spread out the numbers are.
