A store reports that sales increased after a new advertisement was launched. Can we conclude that the advertisement caused the entire increase?

Hint
Consider other possible factors.

Answer

No.

Explanation

The increase may have been influenced by seasonality, pricing, promotions, market conditions or other factors. The timing alone does not establish causation.

Step-by-Step Solution

Observation: sales increased after advertisement.
Possible alternative causes exist.
Therefore correlation in timing does not prove causation.
