In Module 4 we study another area of inferential statistics that involves determining whether a relationship between two or more numerical or quantitative variables exist. For example, a business person may want to know whether the volume of sales for a given month is related to the amount of advertising the firm does that month. Educators are interested in determining whether the number of hours a student studies is related to the student's score on a particular exam. Medical researchers are interested in questions such as, Is caffeine related to heart damage? or Is there a relationship between a person's age and his or her blood pressure? As you study Linear Regression and Correlation, post an example where these statistical techniques can be used to best serve your current or future profession.
