**Spearman's Rank Correlation Coefficient**

The image displays a graph and a table related to Spearman's Rank Correlation Coefficient.

### Graph Explanation
The graph is a symmetrical, bell-shaped curve depicting the distribution of Spearman's rank correlation coefficient ($ r_s $). It ranges from -1 to 1, with critical regions shaded on both tails representing $\alpha/2$ (the significance level divided by two). These shaded areas indicate where the critical values lie for determining the significance of the correlation.

### Table of Critical Values
The table lists the critical values of Spearman’s Rank Correlation Coefficient ($ r_s $) for different sample sizes ($ n $) and significance levels ($ \alpha $). The values in the table allow you to determine if your calculated $ r_s $ is statistically significant.

| $ n $ | $ \alpha = 0.10 $ | $ \alpha = 0.05 $ | $ \alpha = 0.02 $ | $ \alpha = 0.01 $ |
|---------|-------------------|-------------------|-------------------|-------------------|
| 5 | .900 | — | — | — |
| 6 | .829 | .886 | .943 | — |
| 7 | .714 | .786 | .893 | .929 |
| 8 | .643 | .738 | .833 | .881 |
| 9 | .600 | .700 | .783 | .833 |
| 10 | .564 | .648 | .745 | .794 |
| 11 | .536 | .618 | .709 | .755 |

**Note:** A dash (“—”) means the critical value is not applicable or not calculated for that situation.

These critical values are crucial for hypothesis testing to determine if there is a statistically significant correlation between two ranked variables.
