| Note that measures of weighted kappa are meaningful only if the categories are ordinal and if the weightings ascribed to the categories faithfully reflect the reality of the situation. The weightings in this case are determined by the imputed relative distances between successive ordinal categories. By default, each of these distances is set at '1'. You are free to change any or all of these distances, though I recommend you do so only if you have good reason for it. |
| Select the number of categories: |
| 1~2 | 2~3 | 3~4 | 4~5 | 5~6 | 6~7 | 7~8 | ⇐ successive ordinal categories |
| ⇐ imputed relative distances | |

Confidence intervals for proportions are calculated according to the Wilson efficient-score method, corrected for continuity. |
