Question

A _____ correlation indicates that two sets of scores tend to rise or fall together—for example, height and weight. A(n) _____ correlation indicates that two sets of scores have an inverse relationship: As one set goes up, the other goes down—for example, time spent brushing teeth and tooth decay.

Answer 1

The correct answer is Positive, negative

A positive correlation indicates that the two variables move together, and the relationship is strong the closer the correlation gets to one. A negative correlation indicates that the two variables move in opposite directions, and that the relationship also becomes stronger the closer to minus 1 the correlation becomes.
