Hello. We want to validate a scale that we elaborated to evaluate oral presentations. The scale is rating in Yes/No. We have these sources of variation:
- Three different curricular units, according to academic year, being evaluated (several and different students within each curricular unit – between subjects)
- Each student has two judges (each judge fulfills one scale – same items)
- We have different teams of judges (one judge could be included in two different curricular units and with different other judges)
- There are 355 students evaluated.
What is the best way to explore this? |

| General analysis questions like this should be asked on a general discussion forum like SEMNET. |
