Which statement reflects proper interpretation when a relation is observed but causation is not established?

Which statement reflects proper interpretation when a relation is observed but causation is not established?

• A. There is a relationship between X and Y, but causation cannot be determined.
• B. X causes Y.
• C. There is no relationship.
• D. The study proves the theory.

Answer: (A)

The key idea is that an observed association does not prove causation. When X and Y move together, you’ve found a relationship, but this doesn’t show which one affects the other or whether a third factor is driving both. Proving causation typically requires evidence of temporal precedence (X occurring before Y), covariation beyond doubt, and ruling out alternative explanations, often through experimental or strong quasi-experimental designs that control for confounding variables. This is why the statement that there is a relationship between X and Y but causation cannot be determined is the best interpretation. The other options overstate what the data show: claiming X causes Y jumps to a causal conclusion without sufficient evidence; saying there is no relationship contradicts the observed association; and asserting the study proves the theory goes beyond what observational findings can justify.
