1. r = -.85 and p<.05 between employment and GPA. What would you conclude from these results?

a. There is a strong negative and statistically significant correlation between employment and GPA among college students. This means that students who work more tend to have lower GPA and vice versa, to small extent.

b. There is a moderate negative and statistically significant correlation between employment and GPA among college students. This means that students who work more tend to have higher GPA and students who work less have lower GPAs.

c. There is a strong negative and statistically significant correlation between employment and GPA among college students. This means that students who work more tend to have lower GPA and vice versa, to large extent.

d. two variables are unrelated.

2. If a research study in biomedical field found a moderate negative and statistically significant relationship between two variables, which of the following statistical parameters would you expect to see?

a. -.48, p<.05

b.  -.48, p<.01

c.  -.68, p<.01

d. 1, p<.01

3. Which of the following tests would you use to explore the relationship between two continuous variables?

a. Spearman's rank-order correlation

b. Point-biserial correlation

c. Pearson’s product-moment correlation

d. Phi correlation

Answer #1

1. r = -.85 and p<.05 between employment and GPA. What would you conclude from these results?

Since the correlation is significant and negative

c. There is a strong negative and statistically significant correlation between employment and GPA among college students. This means that students who work more tend to have lower GPA and vice versa, to large extent.

2. If a research study in biomedical field found a moderate negative and statistically significant relationship between two variables, which of the following statistical parameters would you expect to see?

In moderate -0.68 is considered

c.  -.68, p<.01

3. Which of the following tests would you use to explore the relationship between two continuous variables?

Correlatioin coeffcient is the correct choice
