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 goes up the other goes down; for example, time spent brushing teeth and decay.

Answer 1

positive; negative

Step-by-step explanation:

Positive correlation: It refers to a stable relationship between two different variables falling in the same direction, which means that if the value of one variable decreases the value of the other variable decreases as well and vice-versa. These are indicated by a positive sign.

Negative correlation: It indicates the inverse relationship between two different variables, which means that if one variable decreases the other variable increases, and vice versa. These are indicated by a negative sign.
