What is the relationship between the number of hours a student studied and their score on the test?

only correlation

only causation

both correlation and causation

neither correlation nor causation

Answer 1

The relationship between the number of hours a student studied and their score on the test is likely to be both correlation and causation. This is because as students studied more hours, their scores on the test generally increased. This shows a correlation between the two variables. Additionally, the increase in studying hours likely caused an improvement in test scores, indicating a causal relationship as well.
