What: go-stats-calculator[1] - CLI tool for computing statistics (mean, median, variance, std-dev, skewness, etc.)

Why: I needed a quick way to look at statistics without having to resort to something heavy such as Python + its statistics module or Excel.

Disclaimer: Vibe-coded by Gemini 2.5 Pro and Opus 4.5 but also validated through unit tests and independent verification[2].

Install: Homebrew[3] or GoReleaser built binaries[4].

Demo:

    $ seq 99 322 | stats

    Mean:           210.5
    Median (p50):   210.5
    Mode:           None
    
    --- Measures of Spread & Distribution ---
    Std Deviation:  64.8074
    Variance:       4200
    Quartile 1 (p25): 154.75
    Quartile 3 (p75): 266.25
    Percentile (p95): 310.85
    Percentile (p99): 319.77
