Study examining how much of the variation in blood pressures readings can be explained by the variation in stress test scores.
Regression:
Regression analysis explains whether two variables are related or not and correlation explains the degree of relationship between an independent and dependent variable. R-squared is a statistical measure that represents the proportion of the variance for a dependent variable that is explained by an independent variable or variables in a regression model. That is, it explains to what extent the variance of one variable explains the variance of the second variable.
