How to Remove Outliers in Python? Once identified, outliners need to be removed to make sure that the data to be processed is more precise to make the result better. Z-score Method The Z-score for the value of
In this article, you will not only have a better understanding of how to find outliers, but how and when to deal with them in data processing.
This article is based on my book—I’ll show you the next method to detect outliers in a moment. Check out my new Python bookPython One-Liners(Amazon Link). If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about asingle line of Python ...

Holidays often lead to increased or decreased demand, depending on the type of product. You can add a feature that flags holidays, as demand can vary during these periods. Python # Add a column for holidaysdata['Holiday']=data['Date'].apply(lambdax:1ifxinholiday_dateselse0) ...
2. Capping Outliers This technique is used when you do not want to discard your data points but keeping those extreme values can also impact your analysis. So, you set a threshold for the maximum and the minimum values and then bring the outliers within this range. You can apply this capp...
(μ) and standard deviation (σ) of the data. After calculating Z-scores, we check if there are values with a score higher than the value of absolute 3, since 99.7% of data fall in the range from -3 to 3. In case we find them, those records represent outliers that significantly ...
In the tutorial on How to Create a Histogram with Plotly, you can explore another way of creating a histogram in Python. Box plot A box plot is a data plot type that shows a set of five descriptive statistics of the data: the minimum and maximum values (excluding the outliers), the me...
Python often feels approachable like this, especially for Excel users, and with Copilot’s assistance, it’s even more within grasp. Weather data seems like a promising choice for analysis since it’s gathered consistently over time, enabling us to detect trends or outliers—such as unseaso...
