Read each question carefully and provide the best answer based on your understanding of scatter plots and correlation. For questions involving diagrams, analyze the visual representation to determine the type and strength of correlation.
1. Which type of correlation is shown in the scatter plot below?
Positive correlation
Negative correlation
No correlation
Perfect correlation
2. What kind of relationship is suggested by a scatter plot where the points are scattered randomly across the graph?
Strong positive correlation
Weak negative correlation
No correlation
Perfect negative correlation
3. When two variables tend to increase or decrease together, they have a correlation.
4. If one variable increases while the other decreases, there is a correlation.
5. A correlation coefficient close to 0 indicates correlation.
6. Describe the difference between a strong positive correlation and a weak positive correlation in a scatter plot.
7. If two variables are correlated, it always means that one variable causes the other.
True
False
8. Give an example of two variables that you would expect to have a strong positive correlation. Explain why.
