With practical examples and intuitive explanations, you'll gain the skills to work on real-world datasets and make impactful predictions.

Section-wise Writeup

Section 1: Introduction

The course begins by introducing the dataset and its variables. You’ll learn how to load and navigate the dataset, setting the foundation for effective data analysis.

Section 2: Exploring and Cleaning Data

In this section, you’ll dive into exploratory data analysis (EDA). Topics include renaming variables for clarity, identifying and handling missing values and duplicates, and creating detailed visualizations to uncover patterns in the data. You’ll also explore the relationship between key variables, such as total working years and attrition rates, and use correlation and chi-square tests to assess associations.

Section 3: Identifying Significant Variables

This section focuses on feature selection. You’ll use Information Value (IV) techniques to identify significant variables and refine the dataset for modeling. With the final dataset prepared, you’ll split the data into training and testing sets, setting the stage for predictive modeling.

Section 4: Predictive Modeling

Here, you’ll build a robust predictive model for attrition. Topics include training the model, making predictions on the test set, and evaluating its performance. By the end of this section, you’ll have a complete workflow for predicting employee attrition.

Conclusion

This course equips you with the skills to handle complex datasets, perform detailed exploratory analysis, and build predictive models. You’ll gain a solid understanding of feature selection, statistical testing, and model evaluation, making you adept at solving real-world problems.

Who this course is for:

• HR professionals interested in analyzing employee attrition.
• Data analysts seeking hands-on experience with predictive modeling.
• Students and professionals aspiring to enhance their data science skills.
