Question

Select the correct text in the table.

Each phrase in the table describes two variables which are strongly correlated. Select all phrases that imply correlation without causation.

A. The number of stuffed animals produced at a factory and the number of newborn babies
B. The number of hits by a baseball team in a game and the number of runs they score
C. The number of people at a store and the number of coupons given out
D. The amount of snow plows on the street and the amount of snowfall
E. The number of videos rented and the number of new films in theaters
F. The number of pets in a neighborhood and the amount of grass fields nearby

Answer 1

A, E, and F are correct.

Explanation:

A correlation is a degree to which two or more quantities are linearly associated. Causation indicates that one event results from the occurrence of the other event; i.e. there is a causal relationship between the two events.

A is a correlation but not causation because the number of newborn babies is not caused or changed by the number of stuffed animals. So A is correct.

B is both correlation and causation because the number of runs a baseball team scores is affected or caused by the number of hits. So B is incorrect.

C is correlation and causation because the number of coupons given out is caused or affected by the number of people at the store. So C is incorrect.

D is correlation and causation because the amount of snow plows on the street is affected or caused by the snowfall. So D is incorrect.

E is a correlation but not causation because the number of videos rented is not affected or changed by the number of new films in theaters. So E is correct.

F is a correlation but not causation because the number of pets in a neighborhood is not affected by the number of grass fields nearby. So F is correct.
