State whether there is no correlation, a positive correlation, or a negative correlation between the x and y variables. If there is a correlation, state whether it is most likely due to coincidence, a common underlying cause, or a direct cause.



For a group of English students at the local junior college, the scatter diagram compares the number of correct answers on a test they took(y) and the length of the pencil used to take the test(x).
◦ Negative correlation; coincidence
◦ Positive correlation; coincidence
◦ Positive correlation; direct cause
◦ No correlation
