The sampling strategy described is stratified sampling which involves dividing the population into subgroups (strata) based on some characteristic (in this case education level) and then randomly selecting participants from each subgroup. This method ensures that each subgroup is represented in the sample proportionally to its size in the population and can therefore increase the precision and accuracy of the results.
