Pecentage at each score

Post by Dobby »

Does anyone know roughly how many children get 141?

Its a mathematical normal curve distribution with mean 100, 4SD at 70 and 141. You can work this out approximately if you know how many children sat the examination

Dobby

Parents going through the appeal process will be sent details of how many children achieved each score across the county and for the school the child attends

So, perhaps, someone in that position can post details when to hand.

As Patricia mentions, there will be some statistics provided with the appeal papers. In addition there is usually a graph showing the number of pupils achieving each score. It does not follow a normal distribution curve. There's a huge amount of bunching around 141, and the average is 110 rather than 100.

Someone with an early appeal has shown me a copy of the results graph for 2005, so I now have an answer to Dobby's question. It's not easy to read off the figures precisely, but around 250-252 children scored 141 (by far the highest total).

In descending order the next highest totals (each with around 180-200 children) appear to have been for the following standardised scores:
2nd highest total: score of 113
3rd highest total: score of 105
4th highest total: score of 107
5th highest total: score of 116

The percentage of children scoring 121+ is 30.14%.

A follow-on from the stats provided by Etienne (12% of all passes got 141 marks) ........ how can this be? Shouldn't this be a normal distribution to be statistically valid?
