CEM and CSSE age standardisation
Hi,
Does anyone know if age standardisation is applied to the CCHS CEM and CSSE tests? I've heard various rumours but can't confirm it anywhere.
Thank you !

Re: CEM and CSSE age standardisation
CCHS yes. CSSE, no. I was told that they do look at the results to check, but have never found the need to standardise by age, from a statistical point of view. 'The tests are not age standardised' is part of the answer to one of the FAQs on the CSSE website.littlemissm wrote:Hi,

Re: CEM and CSSE age standardisation
All CEM exams are standardised and all Verbal and Non Verbal Reasoniing exams that I know of. DG

Re: CEM and CSSE age standardisation
Thank you. Does anyone know if the age standardisation makes much difference in CEM if CSSE hasn't found the need to apply it?
Re: CEM and CSSE age standardisation
I am note sure if I am correct on my observation from last year results of CSSE.
I came to a conclusion that CSSE scoring is based on Age Standardization !
One example I could deduce is,
Maths | English | Score | TotalMarks | Percentage | Ratio of Marks/Score
43 | 42 | 340.42 | 85 | 70.83% | 4.004941176
55 | 32 | 337.206 | 87 | 72.50% | 3.875931034
A pupil with lesser Total marks, got higher final score. How can this happen except for having an age standardization in place ?
Correct me if I am wrong.

You are wrong, I'm afraid - if you look at the CSSE website, you will find the statement that age standardisation is not usedypkr wrote:I am note sure if I am correct on my observation from last year results of CSSE.

Correct me if I am wrong.
The two papers are treated individually - they have a different mean and standard deviation, so for example a difference in raw score of 2 marks in the English paper will have a different effect on the overall standardised score than the same difference in the Maths paper. Look back in the Essex section for a post from a member who asked the CSSE for the relevant details and you can see how the overall score is calculated - in previous years, this was 'Aang', but last year someone else asked, I'm afraid I can't remember who but it was very soon after the results day in October.
Your calculation re '%' etc doesn't come into it.
ETA - have a look at Blitz's post on the last page here, which includes an explanation of how the standardised score is calculated:

Re: CEM and CSSE age standardisation
Thanks a lot Toadmum, for correcting me.
I forgot about that standardization over mean which was posted earlier.
