❓ Frequently Asked Questions
What is the difference between average and mean?
In everyday conversation they are synonymous with the arithmetic mean. In formal statistics, "average" can occasionally refer to other measures of central tendency like the median or mode.
How do extreme outliers affect the average?
The arithmetic average is sensitive to outliers. A single very large or small number pulls the average toward it. In skewed datasets, the median provides a more robust indicator of central tendency.
Can negative numbers be averaged?
Yes. Negative numbers are summed algebraically with positive numbers before dividing by the count.
How do you calculate an average of averages?
You can only average two averages directly if both original groups had the exact same sample size. If group sizes differ, you must compute a weighted average.
Does the calculator support decimal numbers?
Yes. You can enter arbitrary positive or negative decimal numbers with full floating-point precision.
How accurate is the result?
Results use JavaScript's 64-bit floating point — accurate to 15+ significant digits for most calculations.
Can I enter decimal numbers?
Yes, decimals are fully supported.
Is it free?
Yes, completely free.
Does it show the formula?
