FAQ

When should I use median instead of mean?

Use the median for skewed data or outliers (like incomes or house prices). A single billionaire drags the mean up but barely moves the median.

Can there be more than one mode?

Yes — if two or more values tie for most frequent, the dataset is bimodal or multimodal. If every value appears once, there is no mode.

Can mean, median and mode all be equal?

Yes — in symmetric distributions like the bell curve, all three measures of center coincide.

Calculate sample and population standard deviation, variance, mean and standard error from any list of numbers.

Calculate nPr (ordered arrangements) and nCr (unordered selections) with factorials, for probability and combinatorics.

Compute probability of two events: union (A or B), intersection (A and B), conditional probability, and odds.

Standardize any raw score by finding how many standard deviations it sits from the mean.
