Calculation path

Calculate a weighted arithmetic mean from three values and frequencies. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

x_bar=sum(fx)/sum(f)

What you provide

What you provide

  • First value, using the same scenario as the other inputs

What you receive

What you receive

  • Weighted mean from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Use one consistent dataset or scale and verify statistical or geometric assumptions before interpretation.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
