Outliers are values at the extreme ends of a dataset. Some outliers represent true values from natural variation in the population. Other outliers may result from incorrect data entry, equipment malfunctions, or other measurement errors. An outlier isn’t always a form of dirty or incorrect data, so you have to be careful with them in data cleansing...
We’ll walk you through the popular IQR method for identifying outliers using a step-by-step example. Your dataset has 11 values. You have a couple of extreme values in your dataset, so you’ll use the IQR method to check whether they are outliers.
Once you’ve identified outliers, you’ll decide what to do with them. Your main options are retaining or removing them from your dataset. This is similar to the choice you’re faced with when dealing with missing data. For each outlier, think about whether it’s a true value or an error before deciding. 1. Does the outlier line up with other measureme...
