Carefully analyze each scatter plot and question. Determine the type of association, its strength, and whether it is linear or non-linear. Answer all questions thoroughly.
1. For each scatter plot below, identify the type of association (positive, negative, or no association).
Association Type:

2. Which of the following describes a strong negative association?
As x increases, y generally increases, and the points are close to a line.
As x increases, y generally decreases, and the points are widely scattered.
As x increases, y generally decreases, and the points are clustered tightly around a line.
There is no clear pattern between x and y.
3. If a scatter plot shows points generally going downwards from left to right, it indicates a association.
4. A association means that as one variable increases, the other variable also tends to increase.
5. When points on a scatter plot form a curve instead of a straight line, the association is described as .
6. Describe the difference between a strong association and a weak association in a scatter plot.
7. Give a real-world example of two variables that would likely have a positive linear association. Explain your reasoning.
8. A scatter plot with no clear pattern between the variables indicates a strong correlation.
True
False
9. If a scatter plot shows a perfect straight line, it represents a perfect linear association.
True
False
10. Plot the following data points on the graph below and describe the association you observe.
Data: (1, 8), (2, 7), (3, 6), (4, 5), (5, 4), (6, 3), (7, 2), (8, 1)
