1You notice a correlation coefficient of .02 between two variables you are studying. What conclusion should you reach about their relatedness?
- AThe two variables are pretty much unrelated to one another; scores on one variable show no consistent pattern with scores on the other variable.
- BThe two variables show a near-perfect positive correlation; high scores on one variable are associated with high scores on the other.
- CThe two variables show a near-perfect negative correlation; high scores on one variable are associated with low scores on the other.
- DA correlation of .02 means that the data should be reexamined using a different sample of research participants.
2A negative correlation coefficient indicates that as scores on one variable __________, scores on the other variable __________.
- Alevel out; decrease
- Bincrease; decrease
- Cdecrease; decrease
- Dincrease; increase
3Which of the following values for a correlation coefficient indicates the strongest degree of relationship?
- A-.69

- D+.59
4Roya believes that every time the moon is full, her left knee feels shaky. “It’s true,” she insists. “My knee is shaky when the moon is full, and not shaky when the moon isn’t full.” Because there is probably not a reliable association between lunar phases and joint mobility, what does Roya’s belief illustrate?
- Avariable skew
- Ba positive correlation coefficient
- Can illusory correlation
- Da negative correlation coefficient

- AVariable A and Variable B are correlated with one another
- BVariable B causes Variable A to happen
- CVariable A causes Variable B to happen
- DVariable C causes both Variable A and Variable B to happen
