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...

Oct 4, 2022 · Sort your data from low to high. Identify the first quartile (Q1), the median, and the third quartile (Q3). Calculate your IQR = Q3 – Q1. Calculate your upper fence = Q3 + (1.5 * IQR) Calculate your lower fence = Q1 – (1.5 * IQR) Use your fences to highlight any outliers, all values that fall outside your fences.

Apr 27, 2024 · If we recall the outlier formula from the previous section, we'll see that we need the interquartile range. IQR = Q3 - Q1 = 62 - 42 = 20. Lastly, we need to determine the limits for the outliers. According to the outlier definition in math, in our case, an entry x is an outlier if either. x < Q1 - 1.5 * IQR = 42 - 1.5 * 20 = 42 - 30 = 12. or
Jun 28, 2024 · Understanding outliers. Outliers are data points that fall far outside the normal expected range of values in a dataset. They can occur due to various reasons, such as measurement errors, natural variability, or unique circumstances. Outliers can lead to skewness in statistical analysis which then leads to inaccurate results and conclusions if ...

Apr 9, 2022 · Steps for making a box plot (with outliers) Draw the box between Q1 and Q3. Accurately plot the median. Determine possible outliers that are more than 1.5 interquartile ranges from the box. Lower Inner Fence = Q1 – (1.5)IQR. Upper Inner Fence = Q3 + (1.5)IQR. Mark outliers with a special character like a * or •.
