Statistics for Data Science 1 - W4_L4: Association between two numerical variables - scatterplot

Welcome to Week 4 Lecture 4 of the course "Statistics for Data Science - I" by Prof. Andrew Thangaraj. Full Course: https://study.iitm.ac.in/ds/course_pages/BSMA1002.html Video Overview Explore how to analyze the relationship between two numerical variables using scatter plots. This lecture introduces the concept of bivariate numerical analysis, explaining how to create and interpret scatter plots to visualize associations in data. Learn how to identify explanatory and response variables, assess the direction and strength of associations, and extend the idea to multivariate relationships. The session also highlights how scatter plots can reveal underlying patterns and trends essential for deeper data interpretation and statistical analysis.
