Abstract The use of weighted agreement factors in the significance testing of lanthanide‐induced shift analysis is physically meaningless, and can manipulate the resulting significance values, as confirmed by the results found with two compounds. The Hamilton ℛ factor ratio significance test and the jacknife test are compared for these compounds. The ℛ ratio test is more easily applied; the jacknife test does not show any clear advantage and is more sensitive to changes originating from the use of weighted agreement factors.
