what is 68.7% and this modelling ... going to be a late night...if you want to hear something funny. I'm a mature student, yes that's funny but also i turned up for the exam at my local high school this morning. (had the day booked off work aswell ) gutted...... thought last night was my last ever night of revision!!!!! and i cant get tomorrow off so im now pulling a sicky ahahhhhhh
68.7% of values lie in the range (mean+/- standard deviation), I think?! What I meant by modeling was the mathematical model stuff in chapter 1 of the edexcel endorsed textbook( nearly never comes up...), like how to design a mathematical model or what advantages are of mathematical models.
Best of luck to you, just don't do better than me...
