Maths Data Handling

"It's a good, standard piece of GCSE statistics coursework. The maths is most definitely sound. There is a range of data analysis techniques used; it's a shame that saving it to be put on the internet has lost some of the more ambitious graphs. The author gets occasionally confused between the different hypotheses that are going on. They use stratified sample to consider the school as a whole, which is excellent, but they use this same sample when they are comparing and contrasting the data gathered between boys and girls, which means comparing data between a sample of 49 and 51 students. They also fail to consider one quite sizeable problem in this tally... the data that they get is a bit meaningless. "On average, boys in this story are taller than girls" which is a bit vague, as it doesn't take into account whether boys are older on average etc. On the surface, it's a solid piece of work, but it doesn't step out much from beyond the safe statistical analysis to actually consider what the statistics are meaning to show, or do.
