Question

A study of community pools shows a positive correlation between the number of diving boards at the pool and the maximum capacity of the pool. Which variable is most likely the lurking variable that explains the correlation?

Answer 1

Yes the answer is indeed "The area of the pool"
I just took the test and got it correct I even reviewed it.

Answer 2

The answer is the 'Area of the pool'

Explanation:

The diving board is an elevated board that is used for diving and it is placed where the depth of the water has a minimum of 12 ft deep for a 1 meter diving board, with the width of the pool at least 16 feet and the length at least 32 feet.

The maximum capacity is a a function of the Area of the pool and the area of the pool can be calculated with:

Length x width = Area of a Pool.

The Area of the pool is a lurking variable and it best explains the correlation between maximum capacity and the number of diving boards at the pool.
