Wondering how your raw test scores turn into domain scores and your C-Score? It goes a little something like this:
- You play a challenge and get some raw test scores—for example, 60 in Feature Match and 6 in Digit Span.
- Those scores are compared to a database and put on a common scale, so they can be compared to each other. For example, a 60 in Feature Match is not 10 times better than a 6 in Digit Span—the 60 is actually much worse compared to the database average, which is captured by putting the scores on the same scale.
- These new scores contribute a certain amount to each domain score. For example, Feature Match contributes most to reasoning, but also a bit to short-term memory and verbal ability.
- When the contributions from all tests have been counted, you have three domain scores: a reasoning score, a short-term memory score, and a verbal ability score. You can view these on your Brain Report or trend graphs at any time.
- Domain scores are multiplied to produce your C-Score. Thus, the C-Score is a quick summary of your cognitive performance in all three domains. Learn more about how the C-Score is calculated here.
- Percentile scores are also available, comparing your scores to the Cambridge Brain Sciences community. Read more about who you are being compared to here.
That's all there is to it: the C-Score is calculated from domain scores, which are calculated from test scores.
