Let’s say you wanted to find out which subjects Pakistan school children preferred which cartoons. A population list — a list of all Pakistan school children– would be near-impossible to come by, so you cannot take a sample of the population. Instead, you divide the population into states and take a simple random sample of states. For the next stage, you might take a simple random sample of schools from within those states. Finally you could perform simple random sampling on the students within the schools to get your sample. 10/14/2022 Muhammad Awais (facebook.com/awwaiis)

If you want to do interviews on telephone, do demographic quotas to select your respondents. Which means that a certain percentage of all respondents must be of a certain gender or age. In this type of study, researchers determine which person in the household should answer the questionnaire by using a form of random-numbers table. 10/14/2022 Muhammad Awais (facebook.com/awwaiis)
