AP PSYCHOLOGY

Detailed explanation-1: -A positive correlation exists when two variables operate in unison so that when one variable rises or falls, the other does the same. A negative correlation is when two variables move opposite one another so that when one variable rises, the other falls.

Detailed explanation-2: -An example of positive correlation would be height and weight. Taller people tend to be heavier. A negative correlation is a relationship between two variables in which an increase in one variable is associated with a decrease in the other.

Detailed explanation-3: -The correlation coefficient is measured on a scale that varies from + 1 through 0 to – 1. Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative.

Detailed explanation-4: -A positive correlation exists when two variables move in the same direction as one another. A basic example of positive correlation is height and weight-taller people tend to be heavier, and vice versa.
