Question

Gracie, a researcher, is interested in analyzing the relationship between smoking and life span. The results of her correlational study indicate that as the number of cigarettes smoked per day increases, life span decreases. This is an example of the _____ kind of correlation.

Answer 1

This is an example of the "negative" kind of correlation.

A negative correlation implies that there is a reverse connection between two variables - when one variable reduces, the other increases. The other way around is a negative correlation as well, in which one variable increments and alternate declines. These connections are considered in measurements as a methods for deciding the connection between two factors.
