Question

Let’s supposed that we want to choose a random sample of library books. There are four ways we can choose the random sample. Based on 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 each bookshelf and use a random number generator to pick some bookshelves. All the books on the shelves that are picked will make up our random sample

.b.We first organized the books into two groups: fiction and non-fiction. We then number each fiction book and use a random number generator to pick some fiction books to be in our sample. We do the same for the non-fiction books.

c.We number each book and use a random number generator to pick books to be in our sample.d.We number each book and use a random number generator to pick one book. Then we will count off every 10thbook from that starting point to be in our sample.
