使い方

  1. 1
    Paste your data

    Numbers separated by commas, spaces, tabs, or newlines - mixed separators are fine.

  2. 2
    Read the summary

    Central tendency (mean, median, mode), spread (range, variance, std deviation), and totals appear instantly.

  3. 3
    Use the right form

    Sample stats (n−1) when your data is a subset of a larger population. Population stats (n) when it's the full population.

よくある質問

Sample vs population - which do I use?

If your numbers are the entire population you care about, use population (divide by n). If they're a sample and you want to estimate the population, use sample (divide by n−1). Excel STDEV.S = sample; STDEV.P = population.

What if there's no mode?

If every value appears exactly once, the tool reports “no mode.” If two or more values tie for the highest count, they are all listed.

Is my data uploaded?

No. All calculations run entirely in your browser.
