Sampling

How to stratify a sample for GCSE maths

[MrArnoldsMaths]

Depends on the model. It's usually on the left side of a calculator and might say a/b

[joemag]

what if you round them correctly and when they add up, it is more than your total sample size?

Arnold how do you type up fractions to divide on sharp calculator?

[Duqhan]

I don't understand how did you find the sampling question for the second last question. Sample size was 5%. How did you find it

[Eideticspace]

how did you find out the 5% sample size in the last set of questions??
