Mean, Median & Mode Calculator — Full Descriptive Statistics

Enter any list of numbers to instantly compute mean, median, mode, standard deviation, variance, range, skewness, and a frequency distribution table — the complete descriptive statistics toolkit for a dataset. Most calculators only give you mean and maybe median. This one computes all core measures of central tendency, dispersion, and distribution shape, plus a frequency table that shows how often each value appears and what percentage of the dataset it represents. The distribution shape analysis tells you whether your data is symmetric, right-skewed (long tail toward high values), left-skewed (long tail toward low values), or bimodal (two peaks) — context that affects which measure of center is most meaningful for your situation. When data is skewed, the median is a more robust measure of center than the mean because it is not pulled by extreme values. Understanding skewness matters for grading on a curve, analyzing salary data, or evaluating any dataset where outliers are common.
