50% fail

24C, hot & humid.

Education panic: BBC 30% of 10 year olds fail to reach the “expected” level in maths & literacy. Erm, this is where I need to call on the services of a statics expert. Remember in the Labour Govt Ed Balls wanted most kids to achieve “above average (mean)” results? So with results scattered on a Normal Distribution curve, shouldn’t there be about 30%percentage reaching only the arbitrary “expected” level anyway? If you’re comfortable handling standard deviations, then perhaps you could post me an informative link. My competence with bell-curves falls below the required standard I have to say!

What I suspect here is that we are dealing with politicians’ stats rather than competently functioning data handling. (It’s not just me that feels uneasy)

I recall as a kid leaving primary school my own reading age test result was considerably below my chronological age. I’m sure I now have a reading age considerably above 46 years. So the problem was only really a problem for the school, not for me. On the other hand, statistics abuse is a real problem in journalism and politics in the last few decades.
