Average & Statistics Calculator

This statistics calculator instantly computes ten key descriptive statistics from any list of numbers. It handles any reasonable dataset size and accepts numbers separated by commas, spaces, semicolons, or newlines for maximum flexibility.

The mean is the arithmetic average. The median is the middle value when sorted, which is more robust to outliers. The mode is the most frequently occurring value(s). Range shows the spread from min to max. Variance measures how far values deviate from the mean on average (squared), while standard deviation is its square root — the most common measure of spread.

Whether you're a student analyzing a dataset, a teacher checking exam scores, or a data analyst doing quick exploratory analysis, this tool provides the essential statistics you need at a glance.
