How to use the Descriptive Statistics Calculator

  1. Enter or select: Data set.
  2. The results (Count n, Sum, Mean xΜ„, Median, Mode, Minimum, Maximum, Range, Sample std. deviation s, Population std. deviation Οƒ, Sample variance sΒ², Q1, Q3, IQR, Standard error, Skewness, Geometric mean, Coefficient of variation) are calculated instantly as you type.

Formula

  • xΜ„ = Ξ£x/n
  • s = √(Ξ£(x βˆ’ xΜ„)Β²/(n βˆ’ 1))
  • Οƒ = √(Ξ£(x βˆ’ ΞΌ)Β²/n)

About this tool

Quartiles use linear interpolation (the same method as Excel's QUARTILE.INC and NumPy's default).
