In S1 the the rounding is always varying from question to question does anybody know what is the standard rounding requirement.
Sometime it's 3SF for like regression and PMCC. Then for Standard Deviation it's 1DP. So I'm not entirely sure what the principle of rounding is for this module.
Does anybody know for sure?

What I tend to do in that situation is if it doesn't say, round to 2 or 3 decimal places but always use the exact answer as shown on the calculator in further working for subsequent sections of the question.
