A researcher investigates the relationship between minority stress and depression. He collects data from 15 individuals and finds a correlate coefficient of r = .55. Please determine the direction & strength of the relationship and statistical significance at an alpha level of .05.

a. There is a statistically significant large, negative relationship between minority stress and depression, r = .55, p < .05

b. There is a statistically significant large, positive relationship between minority stress and depression, r = .55, p < .05

c. There is no statistically significant relationship between minority stress and depression, although the relationship appears large and positive, r = .55, p > .05

d. There is a statistically significant medium, positive relationship between minority stress and depression, r = .55, p < .05

Answer #1

Solution:

The correct option is:

d. There is a statistically significant medium, positive relationship between minority stress and depression, r = .55, p < 0.05

Explanation:

The test statistic is:

The p-value is:

Since the p-value is less than the significance level, we, therefore, reject the null hypothesis and conclude that there is a statistically significant medium, positive relationship between minority stress and depression, r = .55, p < .05

For a sample of 10 individuals, a researcher calculates residuals for the relationship between “number of delinquent friends” and “number of prior arrests” and finds that the positive residuals = 125. The researcher then collects a second sample of 10 individuals and calculates the residuals on the same two variables and discovers the sum of the positive residuals = 75. What can you conclude about the strength of the relationship between “number of delinquent peers” and “number of prior arrests”...

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...
