In a sample having 23 pairs of observations, the correlation coefficient is 0.52 and in another sample having 28 observations, the correlation coefficient is 0.71. Is there significant difference between the two sample coefficients?
| A. | 5% level is not proper |
| B. | Difference is not significant |
| C. | Difference is significant |
| D. | 95% level is significant |
Answer : B Explanation : N1 = 23, r1 = 0.52 N2 = 28, r2 = 0.71 Z1 for r1 = 0.52 (By reference to table) = 0.58 Z2 for r2 = 0.71 (By reference to table) = 0.89
The difference is not significant at 5% level of significant. Hence the answers (b).
