About Statistics Calculator

The Statistics Calculator is a free browser-based tool that computes key descriptive statistics from a numeric dataset in one click. It is the quickest way to understand your data without installing specialized software or writing code.

The tool calculates 20 statistics in total: 8 basics (count, sum, mean, median, mode, min, max, range), 5 measures of dispersion (population variance, sample variance, population standard deviation, sample standard deviation, coefficient of variation), 3 quantile measures (Q1, Q3, IQR), and 2 shape measures (skewness and kurtosis). Additionally, it automatically detects outliers using the 1.5×IQR rule, helping you spot anomalies quickly.

Simply paste your numbers separated by commas or newlines — column data copied from Excel or Google Sheets works directly. You can click the "Sample Data" button to try different distribution patterns. All computation runs entirely in your browser; no data is ever sent to a server. Statistical results can be exported as CSV for use in reports and analysis.

Perfect for report writing, research data summarization, quality control (QC) analysis, and statistics education.
