WebCan IQR be negative? No, because Q3 will always be greater than Q1. How do you determine outliers using IQR? Subtract or add the IQR value to the corresponding quartile- if it falls within that range, it is not an outlier. ... (0,1) … The interquartile range of a continuous distribution can be calculated by integrating the probability density function (which yields the cumulative distribution function—any other means of calculating the CDF will also work). The lower quartile, Q1, is a number such that integral of the PDF from -∞ to Q1 equals 0.25, while the upper quartile, Q3, is such a number that the integral from -∞ to Q3 equals 0.75; in terms of the CDF, the quartiles can be defined as follows:
