Question

Which situation describes a correlation that is not a causal relationship?

(1) the number of miles walked and the total Calories burned
(2) the population of a country and the census taken every ten years
(3) the number of hours a TV is on and the amount of electricity used
(4) the speed of a car and the number of hours it takes to travel a
given distance

Answer 1

(2) the population of a country and the census taken every ten years. Because even though they are kind of related, one doesn't cause or result from the other.
