Sample vs population standard deviation?
Sample SD divides by n−1 (use when your data is a sample of a larger group). Population SD divides by n (use when you have the entire population).
What is mode if no number repeats?
There is no mode — every value appears once. Our tool shows "none" rather than an arbitrary first value.
When is median better than mean?
With skewed data or outliers. Median income is more representative than mean income because a few billionaires distort the mean.
