Explanation:

This kind of research separates the participants into subgroups exclusively

The number of participants in each subgroup must be defined next , this proportion is then used in choosing subjects from each subgroups

These participants chosen from a larger population must be representative of the original whole population. The traits and characteristics of each group are then studied

This is how one goes about doing a quota sampling research .

Step 1:

Firstly they will choose which population their research is focused on or people who have similarities. As they get participants into strata it must be done exclusively which means there must be no interference between members of each groups.

Step 2:

Then decided how many participants are going to be in each group that is deciding on the proportion of each subgroup.

Step 3:

The sample size is then defined based on the established proportions. Such as when you have decided to sample 1000 people one may chooses 100 for quota sample.
