Question

A study finds a positive correlation between the number of traffic lights on the most-used route between two destinations and the average driving time between the two destinations.
which statement is true ?


a. the correlation is most likely a coincidence


b. the correlation is most likely a causation.


c. the correlation is most likely due to a lurking variable

Answer 1

Increasing the number of traffic lights on the most used route between the two destinations will increase the amount of time it will take to reach to the other destination, as each traffic light will cause a delay. Therefore, the increasing number of traffic lights are causing an increase in the average time to travel to the other destination.

In this case the correlation is most likely a casuation as the increase in the number of traffic lights is causing an increase in the average driving time between the two destinations.

So, the correct answer is option B
