I am trying to establish a correlation between Age-Standardised Score and Raw Score for CEM test. The existing data posted on Birmingham and Warwickshire regions, shows the following correlation (viewtopic.php?f=11&t=25674
):% Raw Score = 0.9864 x Standardised Score – 50.9
The above correlation could be a used to estimate the raw percentage needed to obtain a minimum Age-Standardised pass mark. However, to improve the correlation, I need more data and I would be grateful for the following information:Raw Score
Year of the test
Child birthday or age when test was taken.
If any one does not want to post the data in open, please reply by a private message.
