The main skills covered in Processing were about being able to carry out the basics of statistical analysis. It can seem daunting to be faced with apparently complex data problems. But,as this section tried to show, by following some simple rules, you can take the stress out of summations (and other techniques, too).

Whether it's to do with something as basic as BEDMAS, as central to data as mean, median or mode, or as advanced as normal distribution, you ought to have been able to find something to interest you.

Now to conclude this section, why not have a go at a worksheet on normal distribution.
