Correlation Co-Efficient

[flip_flop]

I have my nephew staying with us at the moment and he's struggling with his homework.

He showed me and the maths is way way beyond my meagre 'O' Level understanding.

Therefore does anybody know of a website which provides an easy to follow step-by-step process to explain how to do/understand these?

Thanks in advance.

Has this to do with fitting a curve to a set of data?

The linear association between two variables.

I assume he's doing A level maths. Does he have access to the MyMaths website? (www.mymaths.co.uk)
Most schools use it but I'm not sure whether it's a spopular at sixth form colleges. He would just need his log in details to access the Correlation bit. It is very good and will take him/you through step by step
