Use the following information to answer items 23 - 27.
n = 227, α = .05, two-tailed
df = n - 2
Relationship | r |
Self-Esteem and Depression | - 0.372 |
Self-Esteem and Social Connectedness | 0.414 |
Depression and Social Connectedness | - 0.619 |
What is the value of the correlation coefficient for the relationship between Depression and Self-Esteem?
QUESTION 24
Using Chart B4, what is the critical r for this study?
QUESTION 25
Would you reject the null hypothesis for the relationship between Depression and Social Connectedness?
QUESTION 26
How much of the variance is explained by the relationship between Depression and Self-Esteem?
QUESTION 27
Write up the summary statement for the relationship between Self-Esteem and Social Connectedness:
r() = , p .05, r2 =
The correlation coefficient value Depression and Self-Esteem is,
Relationship | r |
Self-Esteem and Depression | -0.372 |
24)
The critical value for the correlation coefficient for degree of freedom = n-2=227-2=225 is obtained from correlation coefficient critical value table
25)
Since the correlation coefficient value is greater than r-critical value, the null hypothesis is rejected. Hence there is a significant correlation is between Depression and Self-Esteem.
26)
The r-square value gives the value of variance explained by the relationship between Depression and Self-Esteem.
Hence 13.84% variance is explained by the relationship between Depression and Self-Esteem.
27)
The correlation coefficient value between Self-Esteem and Social Connectedness is,
Relationship | r |
Self-Esteem and Social Connectedness | 0.414 |
The critical value for the correlation coefficient for degree of freedom = n-2=227-2=225 is obtained from correlation coefficient critical value table
Since the correlation coefficient value is greater than r-critical value, the null hypothesis is rejected. Hence there is a significant correlation is between Self-Esteem and Social Connectedness.
And the r-square value is,
Hence, the total variance explained by the relationship between Self-Esteem and Social Connectedness is 17.14%
