Frequently asked questions

Mean vs median — which to use?

Median resists outliers: one billionaire skews a town's mean income but barely moves its median.

What if no value repeats?

Then there is no mode — the tool says so rather than inventing one.

Sample vs population SD?

Population divides by N (used here); sample divides by N−1. For large lists the difference is small.

What is the difference between mean and median?

The mean is the sum divided by the count; the median is the middle value when sorted. For skewed data — like salaries — the median is often more representative.
