Explanation:

• Correlation: The points on the scatter - plot fall along a straight line, which indicates a linear correlation between the time spent studying and the quiz scores.
• Causation: Intuitively, spending more time studying (assuming effective study) is likely to cause an improvement in quiz scores.
