- Explain the difference between correlation and causation. Two variables that are linearly related are positively associated if whenever the value of one variable increases the value of the other variable also increases two variables that are linearly related are negatively associated if whenever the value of one variable increases the value of the other variable decreases. Chapter 4 Section 1 When we have two variables they could be related in one of several different ways They could be unrelated One variable the explanatory or predictor variable could be used to explain the other the response or dependent variable One variable could be thought of as causing the other variable to change In this chapter we examine the second case.

A _____ is a graph that shows the relationship between two quantitative variables. If r 1 or -1 there is a perfect positive negative linear relation between the two variables. Chapter 4 Describing the Relation between Two.

Step 2 Find the critical vale in Table II from Appendix A for the given sample size. The closer r is to 1 or -1 the stronger the evidence of positive negative association between the two variables. If r is close to 0 there is no evidence.

Two variables that are linearly related are negatively associated when above-average values of one variable are associated with below-average values of the other variable.
