Not getting why we divide by 3. Unsure how it gives a mean at 100 as we didn't get told the mean score was 300 for the Trafford consortium (unless I missed it somewhere).Divide by 3 because that gives you a mean set at 100. So what you would expect to see (with a range of c.69 to c.140 and c.68% falling between 85 and 115)
I understand that there were 140 questions in the exam, but each school gave different scores. Sale gave a score 5 higher than Alty for my son. Stretford 5 higher than Sale. I just wish they told us the max score or gave something certain than us guessing that dividing by 3 is it as that fits the tables online and makes most sense.
