There are 3127 maintained secondary schools in England and a further 814 in Wales, Scotland and Ireland. As 12% of the secondary population are educated independently, and indies tend on the whole to be smaller than state secondaries, it's conservative to add to the 3941 state secondaries a further 459 indies, round down a bit and call it 4400, which equates to a 90/10 split of schools.
A professor, no less, of Religious Education sets out to evaluate funding and teaching practices. He visits 24 schools. From this, he makes grand statements about funding, crises, etc, etc.
24. Out of 4400. He's not getting this "statistics" business, is he?
