فيديو شرح Outlier detection and removal using IQR Feature engineering tutorial python # 4 ضمن كورس لغة الآلة شرح قناة codebasics، الفديو رقم 42 مجانى معتمد اونلاين
IQR is another technique that one can use to detect and remove outliers. The formula for IQR is very simple. IQR Q3-Q1. Where Q3 is 75th percentile and Q1 is 25th percentile. Once you have IQR you can find upper and lower limit by removing this formula,
lower_limit Q1-1.5IQR
upper_limit Q3 +1.5IQR
Anything less than a lower limit or above the upper limit is considered outlier. We will use python pandas to remove outliers on a sample dataset and in the end, as usual, I have an interesting exercise for you to practice
