Frequently Asked Questions

What is the difference between mean, median, and mode?

Mean is the arithmetic average (sum ÷ count). Median is the middle value when sorted. Mode is the value that appears most often. Each describes data center differently.

When should I use median instead of mean?

Use median when your data has outliers or is skewed. For example, median income is more representative than mean income because extremely high earners skew the average.

What does standard deviation tell you?

Standard deviation measures the spread or variability in a dataset — how far individual values typically stray from the mean. A small standard deviation means values cluster tightly around the average. A large one means they're spread out widely. It's the most widely used measure of statistical dispersion.

When should I use population vs sample standard deviation?

Use population standard deviation (σ, divides by N) when you have data for the entire group you're studying. Use sample standard deviation (s, divides by N-1) when your data is a sample drawn from a larger population — the N-1 correction (Bessel's correction) produces an unbiased estimate. In practice, you almost always use sample standard deviation.
