standardisation score help ?

Post by dizzyizzy65 »

Hi can anyone please help me. I have checked back on historical data on how to work out scores and i am really finding it confusing.
My dd has scores for the 2015 entry are maths 46/60 and english 40/60
for the 2016 entry she scored 35/60 and english 38/60
Is there a simple way to work the score out ?

Any help is very much appreciated

Yes, you need the mean and standard deviation scores for each year.

These are
CSSE have kindly responded to my query on the official statistics for 2014 11+ exam for 2015 entry

*******************************************************

11+ Standardisation Report – October 2014

Each pupil's raw scores were standardised (mean=100, standard deviation=15). The values used, in 2014, are presented in the table below.

2014 (2015 entry) Mean Standard Deviation
English __________33.174 __________8.665
Maths __________38.349 __________ 10.709

In each case the calculation proceeds as follows:
Standardised score = (((raw score - mean) /standard deviation) x 15) + 100
Total score = 1.5 x standardised Mathematics + 1.5 x standardised English.

Thus a candidate with average marks on each paper will obtain a total of 300, comprising the results in the two papers weighted 1:1.
and for 2015 (2016 entry)
For all those who are interested I have posted below this year's CSSE mean scores and standard deviation figures.

English: Mean score (out of 60) =30.4783, Standard Deviation = 9.2468
Maths: Mean score =35.9650 (out of 60), Standard Deviation = 12.7833
same calculation as for previous year, just plug your results in to get standardized score for each year.

Hope this helps.

especially this part

Total score = 1.5 x standardised Mathematics + 1.5 x standardised English.

i will keep on trying

I worked out your score for 2014(2015 entry) as 333.79 ish(rounding)

Agreed with Pinkrabbit, thank you.

Basically, you take your ds score for one subject and subtract from this the mean score for that subject. This result you then divide by the standard deviation for that subject. This result, you then multiply by 15, then you add 100 to this, then multiply this result by 1.5.
You then do the same for the other subject. Then add both scores together to get the total standardized score.

The way it is worked out means that it gives a higher overall score, if your ds gets a higher score in the subject which others in the cohort score lower in. At least that is the way I understand it. So, as English usually has a lower mean score, a score of, say 50, is worth more in terms of the final standardized score than a score of 50 in maths.

Hope this makes sense and helps you work out future scores.

Dear Pinkrabbit
Thanks for clarifying. Could anyone know the Standard Deviation and Mean for 2017 Entry. May help know the variance and differences in scores and offer some guesses on how different cut off would be for 2017 Entry. As some are on the edge of the green zones of CSSE data, it would help have some idea on the variance and possible trends for 2017 Entry. The wait is getting too long already.
Will be greatful if you could share any more information or direct who would know this.

You need to contact the CSSE - they appear to have been amenable to a polite request for the information over the past few years.

I've inferred these values from the scores given elsewhere on the website, so they may not be correct, but should be about right.

English mean 29, standard deviation 8.1
Maths mean 33.9, standard deviation 12.0
