1 - About

The chance effect in Statistics is represented by the sampling error.

When something is unsystematic, it's then due to chance. If an error is systematic, it's a bias.

The chance probability is:

  • 50% for a two binary event (tossing a coin).
  • 33% for a three class classification

Chance is another word for random.
