Formulas

  • Mean (μ): sum of all values ÷ count
  • Median: middle value when sorted; average of two middles if even count
  • Mode: most frequently occurring value(s)
  • Variance σ²: mean of squared deviations from mean — population formula uses N
  • Sample variance s²: uses N−1 (Bessel's correction) — use this for samples from a larger population
  • Quartiles: Q1 = 25th percentile, Q3 = 75th, IQR = Q3 − Q1 (used to detect outliers)

When I need statistics calculator for mean median mode, I care about fewer steps. Statistics Calculator keeps mean/median/mode direct; with variance and std dev, follow-up review is easier for visitors coming from search.

I found Statistics Calculator while looking for free online statistics calculator, and the real issue was that quick conversions are easy to calculate with the wrong formula. Variance and std dev and quartiles and IQR are on the same page, so I can quickly check whether the result looks right without stitching several tools together.

For statistics calculator work, the important part is whether the output is easy to verify. Statistics Calculator puts quartiles and IQR up front, it reduces manual conversion and repeated input, and it handles mean median mode work without sending me to another page.
