OCR A quantitative moments help

Hi guys,

I'm doing the quantitative task for our practicals tomorrow morning, and all I know is it's something to do with moments.

I was wondering if anyone has any pointers towards quantitative tasks, eg.

How many significant figures to use

Justifying the amount of significant figures to use

Things they mark you on the graph

Things they mark you on the table

Units in the table.
Use more than half the graph paper.
Sensible scales, multiples of 5 or 10 - or maybe 2.
Use 3sf if unsure about anything.
If something such as g is your limiting factor, you must quote to the fewest number of sfs used in a calculation => in the case of g = 9.81 => 3sf is the number.
