Describing the Relationship Between Two Quantitative Variables Using Scatter Plots

This lesson covers the relationship between two quantitative variables using scatter plots. It begins with an explanation of categorical and quantitative variables, followed by a detailed look at scatter plots and their axes. The lesson explores different shapes that scatter plots can take, such as linear, quadratic, and exponential, and how these relate to function families. Examples include analyzing alligator length and weight data, and cricket chirps in relation to temperature, demonstrating how scatter plots help visualize data relationships.
