Let’s supposed that we want to choose a random sample of librarybooks. There are four ways we can choose the random sample. Basedon descriptions given below, label each as either simple random,stratified random, cluster random, or systematic random .
a.The library books are storedon bookshelves. We number eachbookshelf and use a random number generator to pick somebookshelves. All the books on the shelves that are picked will makeup our random sample
.b.We first organized the books into two groups: fiction andnon-fiction. We then number each fiction book and use a randomnumber generator to pick some fiction books to be in our sample. Wedo the same for the non-fiction books.
c.We number each book and use a random number generator to pickbooks to be in our sample.d.We number each book and use a randomnumber generator to pick one book. Then we will count off every10thbook from that starting point to be in our sample.
