Analyzing Bivariate Data Concepts

This video tutorial covers 8th grade math concepts from illustrative mathematics unit 6, lesson 8. It begins with an introduction to scatter plots, discussing how to draw them and identify outliers. The video then explores different types of associations in scatter plots, such as linear, non-linear, and positive associations. Finally, it analyzes the slope of scatter plots, explaining how to determine if a slope is positive, negative, or zero. The video concludes with a call to action for viewers to subscribe and watch the next lesson.

What is the horizontal axis labeled in the scatter plot for book sales data?

• Number of books sold

• Price in dollars

• Time of sale

• Store location

What is considered an outlier in the book sales data?

• A point close to the line

• A point far from the line

• A point with the highest price

• A point on the line

What happens to book sales as the price increases?

• Sales increase

• Sales remain constant

• Sales decrease

• Sales fluctuate randomly

Which type of association is NOT present in the scatter plot from problem two?

• Negative Association

• Positive Association

• Non-linear Association

• Linear Association

What type of association is present when both variables increase together?

• Negative Association

• Linear Association

• Positive Association

• No Association

What is the slope of the model in problem three?

• Positive

• Zero

• Negative

• Undefined

What does a negative slope indicate about the relationship between two variables?

• Both variables increase

• Both variables decrease

• One variable increases while the other decreases
