Question

ss.o An elementary school has students in kindergarten, first, and second grade. Each grade level has around 120 4. students split up about evenly into 6 classes. (so each grade level has 6 classes of 20 students each) Suppose we wanted to obtain a random sample of between 30 and 60 students from the school. A simple random sample could be obtained by either taking every student, putting their name in a big bag and drawing out the desired number of names- pretty easy! But, getting a cluster sample, stratified random sample, and a systematic random sample would require a bit more detail. For example, a cluster sample could be obtained by taking the 18 total classes as the 18 groups (clusters). We could place pieces of paper numbered 1- 18 in a hat and draw 2 numbers out. We could take every student in those 2 classes as our cluster sample which would give us an acceptable sample size of 40 here. Now it is your turn, choose either systematic sampling or stratified sampling and give a detailed pla sample could be obtained. You must provide enough detail so that I could go out and follow your plan the data. n of how that to collect

Explanation / Answer

I choose systematic sampling.
A systematic sample could be obtained by taking all students name and prepare the list of student's names.
From the list, we randomly select the first sample element from the first 4 elements on the population list. Thereafter, we select every 4th element on the list.
