Mean, Median, Mode, Range Calculator

Compute the four classical descriptive statistics — mean (average), median (middle value), mode (most frequent value), and range (max − min) — from a list of numbers. Paste any list separated by commas, spaces, semicolons, or newlines.

Separate numbers with commas, spaces, semicolons, or new lines. Decimals are fine; scientific notation is not supported.

ResultWhat it means?
—Insufficient dataAt least two numbers are required to compute mean, median, mode, and range meaningfully.
2 – 5Small sample (2 – 5)A handful of values. The mode in particular is unreliable with so few points.
6 – 20Typical sample (6 – 20)A reasonable working sample for a class assignment or quick sanity check.
≥ 21Large sample (≥ 21)A larger sample. Mean and median become more stable; mode may surface clear clusters.
—No resultThe input was empty or contained no valid numbers.

How it works

=

Mean = (sum of values) ÷ count. Median = the middle value (or the average of the two middles for an even count). Mode = the most frequent value(s); shown as "—" when every value is unique. Range = max − min.

Binary CalculatorPerform addition, subtraction, multiplication, or division on two non-negative integers and see the result rendered in any of four numeral systems — binary (base 2), decimal (base 10), hexadecimal (base 16) or octal (base 8). Type the two values as plain decimal numbers; the calculator treats them as if they were written in the chosen system and shows the answer in that same system. For example, with Numeral system = Binary, enter A = 204 and B = 170 to compute 11001100 + 10101010 = 101101110.Percentage CalculatorCalculate percentages in five ways: X% of Y, what percent X is of Y, add or subtract a percentage, and percent change between two numbers. Useful for discounts, tips, interest rates, grade scores, and growth rates.Circle Area CalculatorCalculate the area of any circle from its radius. Pick any unit for the radius — the result is shown in square meters and re-expressed in the unit you chose, so you always see a number that fits the input. Useful for plates, wheels, plots, pizzas, pipes, lenses, and any round surface.Percent Error CalculatorCalculate the percent error between an observed (measured) value and a true (accepted) value. Useful for lab reports, measurement accuracy checks, and forecast-vs-actual comparisons.Rectangle Area CalculatorCalculate the area of any rectangle from its width and height. Pick any unit for each side — the result is shown in square meters and re-expressed in the unit you chose, so you always see a number that fits the inputs you entered. Useful for floors, walls, plots, screens, paper, tiles, and any flat surface.Probability CalculatorCalculate the probability of events A and B (intersection, union, either, neither, or conditional) assuming independence. Enter each probability between 0 and 1, then choose the operation.
