Spearman s correlation Introduction Before learning about Spearman s correllation it is important to understand Pearson s correlation which is a statistical measure of the strength of a linear relationship. Multiple Linear Regression Multiple Linear Regression A regression with two or more explanatory variables is called a multiple regression. This method is often used in scientific or medical experiments More information. Learning objectives Descriptive Statistics F. Correlation and Simple Linear Regression We are often interested in studying the relationship among variables to determine whether they are associated with one another.
