Question

correlation and causation quick check
a student places five books next to each other on their ends. she then pushes the first book with her finger, and a few seconds later, the last book falls. which statement is correct about this chain of events? (1 point)

there is causation between the force of the finger and the number of books.

there is a positive correlation between the force of the finger and number of books.

the acceleration of the books as they fall causes the force of the finger.

the force of the finger causes the books to accelerate and fall.

Explanation:

1. Analyze the first option: The force of the finger and the number of books—there's no causal link here as the number of books doesn't depend on the finger's force in this context. So this is incorrect.
2. Analyze the second option: A positive correlation implies a relationship where as one increases the other does too, but here the force of the finger and number of books don't have such a correlational relationship. So this is incorrect.
3. Analyze the third option: The force of the finger happens first, so the acceleration of books falling can't cause the finger's force (cause and effect are reversed here). So this is incorrect.
4. Analyze the fourth option: When the student pushes the first book with her finger (applies a force), according to Newton's laws of motion, this force causes the books to accelerate (start moving) and eventually fall. This is a correct causal relationship.

Answer:

The force of the finger causes the books to accelerate and fall.
