An ecological investigation was carried out to explore the relationship between soil pH and the density of a wildflower species. The researcher collected data from a sample of 10 distinct quadrats (N=10N = 10N=10).
| Quadrat | Soil pH | Wildflower density (per m2\text{m}^2m2) | Ranks of soil pH | Ranks of wildflower density |
|---|---|---|---|---|
| A | 5.2 | 3 | 1 | 2 |
| B | 5.5 | 2 | 2 | 1 |
| C | 5.8 | 6 | 3 | 4 |
| D | 6.0 | 5 | 4 | 3 |
| E | 6.3 | 9 | 5 | 6 |
| F | 6.4 | 8 | 6 | 5 |
| G | 6.8 | 12 | 7 | 8 |
| H | 7.0 | 10 | 8 | 7 |
| I | 7.2 | 15 | 9 | 10 |
| J | 7.5 | 14 | 10 | 9 |
Write the significance statement for the analysis performed on this data using Spearman's ranked correlation coefficient.
(Note: For this data, the calculated value of rs=0.939r_s = 0.939rs=0.939. For a two-tailed test where N=10N = 10N=10 and p≤0.05p \le 0.05p≤0.05, the critical value is 0.648.)
