Stratification

Hi sir, i’m having some doubts regarding stratification of the audit evidence chapter.

I do understand that it is a process of breaking down the population into smaller sub-populations and each sub-population is a group of items which have similar characteristics.

But, i don’t understand how each sample is extracted.

For example, a population of 14 people, inclusive of 6 males and 8 females will be broken down in 2 sub-populations of 6 males and 8 females respectively right.

So how is the sample extracted ?

Will 2 males, for example make up a sample and be tested. And likewise, 3 females for example, make up another sample and be tested ?

Or

Will a certain proportion be taken from both the strata to form a sample. For example, 2 males and 3 females form a sample. 2 other males and 3 other females form another sample ?

Which is the correct way sir ?

The objective of stratification is actually to increase the representativeness of the sample. Am i right sir ?
