In a survey of youth in southern Minnesota, the following correlations and p value results were found when the students were asked why they were changing schools: n = 175 (df = 173). α = .05. Assume the study is two-tailed, only interested in whether a relationship exists.
| Measures of Correlation for the Desire to Change Schools | Correlation (r ) with Significance |
| Number of fights in the last year | .567, p < .05 |
| Number of students arrested in the last year | .878, p < .01 |
| Alcohol Abuse | -.167, p > .05 |
| Drug Abuse | -.627, p < .05 |
1) what would the coefficient of determination be for the variable Number of Flights?
a) 0.321
b) -0.627
c) 0.567
d) 0.792
| Measures of Correlation for the Desire to Change Schools | Correlation (r ) with Significance | Result |
| Number of fights in the last year | .567, p < .05 | relation exist |
| Number of students arrested in the last year | .878, p < .01 | relation exist |
| Alcohol Abuse | -.167, p > .05 | relation not exist |
| Drug Abuse | -.627, p < .05 | relation exist |
1) Coefficient of determination be for the variable Number of Flights is 0.5672 = 0.321
since the correlation coefficient of number of fights in the least year is 0.567
Correct answer: option (A) 0.321
