The effect of a ‘don't know’ option on test scores: number‐right and formula scoring compared

In multiple‐choice tests using a `don't‐know' option the number of correct minus incorrect answers was used as the test score (formula scoring) in order to reduce the measurement error resulting from random guessing. In the literature diverging results are reported when comparing formula scoring and number‐right scoring, the scoring method without the don't‐know option.
