Read each question carefully and answer to the best of your ability. For scatter plot questions, analyze the relationship between the variables.
1. Which type of correlation is shown in a scatter plot where the points generally rise from left to right?
Negative correlation
Positive correlation
No correlation
Weak correlation
2. What does it mean if a scatter plot shows a strong negative correlation?
As one variable increases, the other variable also increases significantly.
There is no clear relationship between the variables.
As one variable increases, the other variable decreases significantly.
The variables are independent of each other.
3. When a scatter plot shows points spread out randomly with no clear pattern, it indicates correlation.
4. A scatter plot showing the number of hours studied and a test score would likely show a correlation.
5. A strong correlation implies that one variable causes the other.
True
False
6. The closer the points on a scatter plot are to forming a straight line, the stronger the correlation.
True
False
7. Describe a real-world scenario that would likely produce a negative correlation in a scatter plot. Explain why.
8. Examine the scatter plot below. Describe the type and strength of the correlation shown. Justify your answer.
