chi square density calculator online

Use chi square density calculator online for x, degrees. Positive x and degrees of freedom; no significance decision. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter x. Set degrees. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
xMain input. Positive values. 3
degreesOption. Positive values. 4

Calculation method

density = x^(degrees/2-1)*exp(-x/2)/(2^(degrees/2)*gamma(degrees/2)) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply chi square density calculator to the case below, keeping the displayed units and assumptions. Positive x and degrees of freedom; no significance decision.

Output:

{

}

Choose the right tool

Choose number theory for exact integer relationships, distribution tools for a declared random model, and geometry tools for coordinates. A density is not a probability and a statistical model does not establish a real-world outcome.

Limitations and common mistakes

  • Positive x and degrees of freedom; no significance decision. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
