Turning ranks into rulers

Ready to turn your rank into a ruler?

RM Compare produces a rank order as part of the Adaptive Comparative Judgement process. It does by ranking items by their 'true score'.

To use the rank as a ruler we need a scaled score. This will allow us to use the ruler to assess new pieces of work and also opens up the possibility of grading.

Step 1: How do I turn my rank (log scale) into a ruler (linear scale)?

Step 2: How do I calibrate my ruler?

Read more: A worked example of this process is described in a blog post here.

Step 3: How do I use my ruler to standardise new work?
