Our summary
Score helps when possible answers have an order, such as calm, frustrated, and very angry. Jev assigns a probability to every described level, then returns an average position based on those probabilities. The number summarizes the spread rather than measuring the subject directly.
A program can compare scores or combine several questions. Before combining scales of different lengths, it should put them onto the same comparable range. Clear descriptions and examples can sharpen boundaries, but examples should resemble real inputs and be tested on separate material.
A result between two levels does not create a newly measured fact. It only reflects probability spread across the levels supplied. Do not treat that between-level result as an exact measurement, and do not assume a tightly grouped answer is correct without checking known examples.
Key takeaways
- Describe each ordered level in words before using its numbered position.
- Read the score as an average of the probability assigned to each level.
- Put different scales onto a comparable range before combining them, and do not treat a between-level result as an exact measurement.
