The magnitude of the Pearson correlation coefficient indicates the direction of association, while its sign indicates the strength of the association.
 a. True
  b. False

Question 2

In a regression analysis, determining the statistical significance of the slope involves the use of the t-statistic.
 a. True
  b. False

Question 3

The simple regression technique in SPSS, not the researcher, specifies which variable should be the independent variable and which one should be the dependent variable.
 a. True
  b. False

Question 4

In multiple regression analysis, t tests are used to test for the statistical significance of betas. If a beta is insignificant, it means that its respective independent variable plays no meaningful role in predicting the dependent variable and the independent variable should be removed from the model.
 a. True
  b. False

Question 5

The multiple R, also called the coefficient of determination, in multiple regression ranges from 0.00 to +1.00 and represents the amount of the dependent variable explained by the combined independent variables.
 a. True
  b. False

Question 6

Carters, a marketer of children appeal, knows that as girls increase in age, their dress size tends to get larger. This is an example of a causal type of relationship?

Olive Garden restaurants know that customers drink beverages for lunch and alcoholic drinks at supper. This is an example of an associative type of relationship?

Question 8

The manager of New England Patriots conducted a large survey. He wanted to know if there was an association between fans being season ticket holders vs. non-season ticket holders and whether they bought vs. didn't buy team merchandise at the game. Since his survey included these measurements, he used SPSS to run a Pearson correlation coefficient that turned out to be 0.88 with a Sig. value of .001 . This meant there is a significant relationship.
 a. True
  b. False

Question 9

If you have a significant and very strong (e.g., > 0.90 correlation coefficient), you may assume there is a causal relationship between the two variables.
 a. True
