Generate random numbers using three statistical distributions — Integer (discrete uniform), Float (continuous uniform), and Normal (Gaussian bell curve). Supports seeded output for reproducibility, no-duplicates mode, sort order, and instant statistics including mean, median, standard deviation, and mode.
Calculate all six types of mean simultaneously — Arithmetic, Geometric, Harmonic, Quadratic (RMS), Weighted, and Trimmed. Paste any dataset and instantly get the right average for your context, plus median, mode, standard deviation, variance, and coefficient of variation.
Find the median of any dataset instantly, with quartiles (Q1, Q3), IQR, five-number summary, interactive box plot, outlier detection using Tukey fences, percentile table, MAD, and Pearson skewness. Robust central tendency analysis for statistics, data science, and research.
Find the mode(s) of any dataset with a complete frequency distribution table, visual bar chart, and automatic distribution type classification — unimodal, bimodal, multimodal, or amodal. Ideal for statistics, data science, surveys, and educational analysis.
Format, validate, minify, or sort JSON data with configurable indentation. Instantly check for syntax errors, view node count and nesting depth — free, no sign-up required.
