I understand the basics of Standardised Age Scores and Percentiles, but this example has me confused (brain tired with other matters perhaps). Anyhow, thoughts welcome:
(working on basis of 69/70 to 140/141 with 100 as average)
SAS for English 115
SAS for Maths 122
Combined SAS 237 (maximum possible 282)
I would assume individual percentiles to be 84th percentile for the 115 and 93rd percentile for the 122 (using www.nfer.ac.uk/nfer/research/assessment/eleven-plus/standardised-scores.cfm ).
How is percentile worked out on the Combined SAS though?
