Calc. 0 The absolute value distance metric for this applicant is closest to the record 2, which had an outcome of adequate. Distance can be measured a lot of different ways. The most commonly used measure is squared distance, which gives greater emphasis to great distances than to small distances. The distance measure is simply the sum of squares of differences between the record value and the new value over all measures.
