Exploring Positive and Negative Correlation in Scatter Plots

The video tutorial explores scatter plots and different types of correlations: positive, negative, and no correlation. It explains how to identify these correlations in scatter plots using real-world examples, such as the relationship between a child's age and height, or a car's age and value. The tutorial also covers how to analyze scatter plots for trends and correlations, providing practical examples like SUV sales over time and the relationship between TV watching and homework time.

What is a scatter plot?

• A graph that shows a single line.

• A graph that shows a collection of ordered pairs.

• A graph that shows only positive trends.

• A graph that shows only negative trends.
