Hello students, as per the given question we need to match each sampling technique to the corresponding strategies.
00:08
So, for the first one which is given where the researcher gets the complete list from the sensex bureau and survey every 1500th person of the list.
00:24
So, we say that for this the strategy is the sampling technique which is option b systematic sampling.
00:43
So, this would be the much suitable answer for that and for the next one where the researcher gets the complete list from the sensex bureau and uses a computer to randomly select 2000 people out of them.
01:00
So, we say that as per the given question option a is the most suitable for that which is simple random sampling is the technique.
01:22
And coming to the next question where the researcher picks up 20 different small groups a church group, a democrat club, a student club etc.
01:32
So, each containing 100 people each.
01:37
So, then the researcher make sure the everyone from each group answers the survey question.
01:42
So, for this kind of thing we say that option d is the correct choice which is cluster sampling that is because there are different types of groups with a similar kind of with equal number of clusters divided and each of them are surveyed...
