A scatter graph shows that as the daily temperature rises, ice cream sales also rise. What type of correlation is this?
Answer and explanation
Correct answer: B. Positive correlation
- Step 1: Both variables increase together, so the points slope upwards.
- Step 2: This is positive correlation.
Answer
Positive correlation.
Why not the others: Negative correlation: Negative correlation would mean sales fall as temperature rises. No correlation: No correlation would mean no pattern between the variables. Direct causation: Correlation describes a link and does not prove that one variable causes the other; it is not a type of correlation.
