  2. Check the stated assumptions and calculate.
  3. Review each output and compare another input scenario.

Try this example

{
  "ssb": 60,
  "ssw": 90,
  "k": 3,
  "n": 33
}

Accuracy and scope

Independent normal groups with common variance for classical F inference; no p-value computed. Finite floating-point arithmetic; results can lose precision near singular or extreme inputs.
