Standard Deviation

Confidence Intervals

A confidence interval represents our confidence that any given value xx belongs to the set xi..xn{x_i .. x_n}.

It lets us tackle questions like

  • If I give a patient a drug and they get better, how likely was it that they would have got better anyway, i.e. they belong to the set of patients who would have got better anyway.
  • If I give 100 oatients a drud, and 50 of them get better, how likely is it that the drug works?
