This module focuses on preparing data for analysis through essential data wrangling techniques. You will learn how to clean, transform, and format datasets by handling missing values, converting data types, normalizing numerical values, and creating bins for analysis. The module also introduces methods for transforming categorical variables into numerical representations suitable for modeling. Through hands-on exercises, you will apply these techniques to real-world datasets.

This module develops your ability to analyze and understand datasets through exploratory data analysis techniques. You will learn how to calculate descriptive statistics, perform correlation analysis, and apply grouping techniques to uncover relationships between variables. The module also introduces data visualization methods and statistical tests such as the chi-square test for categorical variables. Through practical labs, you will analyze datasets to identify trends, patterns, and potential insights.

This module introduces the fundamentals of building predictive models using regression techniques. You will learn how to construct simple linear, multiple linear, and polynomial regression models to analyze relationships between variables. The module also covers methods for evaluating model performance using metrics such as R-squared and Mean Squared Error. Visualization techniques such as residual plots and KDE plots are used to assess how well models fit the data.

This module focuses on improving model performance through evaluation and optimization techniques. You will learn how to detect overfitting and underfitting and apply strategies to improve model generalization. The module introduces ridge regression and hyperparameter tuning using grid search to refine predictive models. Through hands-on labs, you will evaluate and improve regression models using real-world datasets.

In this module, you will apply the full data analysis workflow learned throughout the course. You will import, clean, analyze, and model real-world datasets to generate insights and predictions. The module includes a practice project and a final project that simulate real data analysis scenarios. You will also complete a final exam to demonstrate your understanding of key concepts in Python-based data analysis.
