WebHere, you will learn a more objective method for identifying outliers. We can use the IQR method of identifying outliers to set up a “fence” outside of Q1 and Q3. Any values that fall outside of this fence are considered outliers. To build this fence we take 1.5 times the IQR and then subtract this value from Q1 and add this value to Q3. WebFor our example, 8.4 falls between 8 and 9, which corresponds to the data values of 35 and 40. Take the difference between these two observations and multiply it by the fractional … orc smoking
