Frequently Asked Questions

What is the difference between mean, median, and mode?
Mean is the sum divided by count (arithmetic average). Median is the middle value when sorted. Mode is the most frequent value. For symmetric data, all three are similar; for skewed data, they can differ significantly.
How many numbers can I enter?
There is no practical limit. Enter as many numbers as you need, separated by commas, spaces, or newlines. The calculator handles them all instantly.
What if there is no mode?
If all values appear the same number of times (no repeats), the calculator reports 'None' for mode. If multiple values share the highest frequency, all are shown.
