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.

What does a positive correlation indicate?

• As one variable increases, the other also increases.

• There is no relationship between the variables.

• The variables remain constant.

• As one variable increases, the other decreases.

Which of the following is an example of positive correlation?

• As the age of a car increases, its value decreases.

• As the number of hours spent watching TV increases, the time spent on homework decreases.

• As the age of a child increases, their height increases.

• There is no relationship between shoe size and batting average.

What does a negative correlation indicate?

• As one variable increases, the other also increases.

• As one variable increases, the other decreases.

• There is no relationship between the variables.

• The variables remain constant.

Which of the following is an example of negative correlation?

• As the age of a child increases, their height increases.

• As the age of a car increases, its value decreases.

• There is no relationship between shoe size and batting average.

• As the number of hours spent watching TV increases, the time spent on homework increases.

What does no correlation indicate?

• There is no relationship between the variables.

• The variables remain constant.

• As one variable increases, the other decreases.

• As one variable increases, the other also increases.

Which of the following is an example of no correlation?

• As the age of a child increases, their height increases.

• There is no relationship between shoe size and batting average.

• As the number of hours spent watching TV increases, the time spent on homework decreases.

• As the age of a car increases, its value decreases.
