Scaled mean is a good indication of how some subjects scale in relation to others.

Hello epic MX2 scaled mean.

(i) The P99, P90, P75, P50, P25 columns refer to the 99th, 90th, 75th, 50th and 25th percentiles respectively

e.g. If you got a raw mark of 43.5 (the marks are out of 50) which is the 90th percentile, then it would get scaled to 35.0.

The reason why people talk about mx2 so greatly is because the 25th percentile (lowest percentile listed) is 39.0 and it scales up to 42.3.
