A box plot allows us to identify the univariate outliers, or outliers for one variable. Box plots are useful because they show minimum and maximum values, the median, and the interquartile range of the data. WebHow do you find an outlier point? Multiplying the interquartile range (IQR) by 1.5 will give us a way to determine whether a certain value is an outlier. If we subtract 1.5 x IQR from the first quartile, any data values that are less than this number are considered outliers.
