Solution: (a) Estimate whether the following pairs of scores for X and Y reflect a positive relationship, a negative relationship, or no relationship.
Question: (a) Estimate whether the following pairs of scores for X and Y reflect a positive relationship, a negative relationship, or no relationship. Hint: Note any tendency for pairs of X and Y scores to occupy similar or dissimilar relative locations.

(b) Construct a scatterplot for X and Y . Verify that the scatterplot does not
describe a pronounced curvilinear trend.
(c) Calculate r using the computation formula (6.1).
