Question from Carolyn, a parent:

If the CONTROL Scorer A scored 5 minutes of Stage 1 sleep, and the compare Scorer B scored 7 minutes of Stage 1 sleep out of the same sample, what is the % similar/same is Scorer B to the Control Scorer A?


If Group A scored 5 minutes and Group B scored 7 minutes, then the ratio of B to A is 7:5, or 1.4:1, which means that the score for Group B is 140% of Group A's score.
