Detailed explanation-1: -Answer and Explanation: Given, the number of hours a person has driven and the number of miles driven. These two have a positive correlation since the count of miles will increase as the number of hours that a person has driven increases. The two variables tend to move together in the same direction.

Detailed explanation-2: -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.

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: -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-5: -Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one’s height increases so does the shoe size.
