#18 Exploratory data analysis | Python for Data Science

128.1K views on YouTube

Welcome to ‘Python for Data Science’ course !

This video focuses on uncovering patterns and relationships within your data. The lecture introduces frequency tables for understanding the distribution of categorical variables, like fuel type in the car dataset (). You’ll learn how to handle missing values when creating these tables.
It then covers two-way tables for exploring relationships between two categorical variables, for example, fuel type and gearbox type. You’ll see how to calculate joint, marginal, and conditional probabilities from these tables to make inferences about variable relationships.
Finally, the video introduces correlation as a measure of association between two numerical variables, using the car dataset to demonstrate its calculation and interpretation. It emphasizes that understanding these exploratory data analysis techniques is crucial for generating hypotheses and deriving meaningful insights from your data.
