Maths Drawing Statistical Graphs on Autograph

First give out the tutorial sheet which guides students through drawing a histogram, cumulative frequency graph and box plots using Autograph when the data has unequal class intervals. Then give out the worksheet and let them have a go at doing it themselves. Good practise for those students studying GCSE Stats before they get going on their controlled assessment but equally appropriate for Higher GCSE (just ignore the bit about standard deviation).
