Can that rounded mean exist?

Ask whether a reported mean or standard deviation passes necessary arithmetic checks for bounded integer observations.

Runs only when you press the button. Input edits discard the previous displayed result. Public compute limits apply.

KNOW WHAT THE RESULT MEANS

Useful evidence needs boundaries.

  • These checks apply only when integer observations and the specified rounding rules describe the data.
  • Passing necessary conditions does not reconstruct a dataset or prove one exists.
  • A flagged inconsistency can reflect transcription or methodological differences; it is not an accusation of fraud.
