Accumulative Advantages & Outliers. Then, to identify outliers, we multiply the interquartile range by 1.5, which in our case equals 2*1.5 = 3. The outliers among the low scores are the scores which are smaller than the smallest score of the interquartile range minus this number; in our example, 118 - 3 = 115.
