How to Replace NaN Values with Mean of Column in Pandas DataFrame: Data Cleaning Tutorial

Can you help me to buy a coffee:

In this tutorial, you will learn how to handle missing values in a Pandas DataFrame by replacing NaN (Not a Number) values with the mean of the respective column. Missing data can often pose challenges in data analysis and modeling, and filling these gaps with meaningful values is crucial to maintain data integrity.

We will explore the step-by-step process of identifying missing values, calculating the column means, and replacing the NaN values with the mean value using Pandas library in Python. This technique allows us to impute missing values efficiently, ensuring that our data remains accurate and representative.

By the end of this tutorial, you will have a solid understanding of how to leverage the power of Pandas to clean and preprocess data by filling missing values with column means. This skill will be invaluable in your data analysis and data science projects, enabling you to derive more accurate insights from your datasets.
