A student organization surveyed both recent graduates and current students to obtain inforamtion on the quality of teaching at a particular university. An analysis of the responses provided the teaching ability ranking shown below. Do the rankinds given by current students agree with the ranking given by recent graduates? Use a .05 level of significance to test for a significant rank correlation.
| Professor | Ranking By | |
| Current Students | Recent Graduates | |
| 1 | 4 | 5 |
| 2 | 6 | 7 |
| 3 | 8 | 8 |
| 4 | 3 | 1 |
| 5 | 1 | 6 |
| 6 | 2 | 4 |
| 7 | 5 | 3 |
| 8 | 10 | 9 |
| 9 | 7 | 2 |
| 10 | 9 | 10 |
Solution
The test hypothesis:
Ho: the rankinds given by current students agree with the ranking given by recent graduates
Ha: the rankinds given by current students do not agree with the ranking given by recent graduates
Based on Spearman Coefficient of Rank Correlation test,
| Current Students | Recent Graduates | ||
| Current Students | 1.000 | ||
| Recent Graduates | .600 | 1.000 | |
| 10 | sample size | ||
