Question

what kind of correlation is this: as the temperature goes up, sales of hot chocolate go down?
no correlation
negative correlation
causation
positive correlation

Explanation:

When one variable (temperature) increases and another (hot - chocolate sales) decreases, it's a negative correlation. Causation implies a cause - and - effect relationship which isn't fully established here just from the correlation. Positive correlation means both variables increase or decrease together, and no correlation means no relationship between the variables.

Answer:

B. Negative correlation
