Define Frame
A frame is a list of the individuals in the population being studied.
define Random sample
A sample of size n from a population of size N is obtained through simple random sampling if every possible sample of size n has an equally likely chance of occurring. The sample is then called a simple random sample. To obtain a simple random sample, typically, each individual in the population is assigned a unique number between 1 and N, where N is the size of the population. Then n distinct random numbers from this list are selected, where n represents the size of the sample. To number the individuals in the population, one needs a frame—a list of all the individuals within the population.
As part of a college literature course, students must read three classic works of literature from the provided list. Write a short description of the processes that can be used to generate a simple random sample of three books. Obtain a simple random sample of size 3 from this list. Which of the following would produce a simple random sample? Select all that apply
Number the books from 1 to 9 and use a random number generator to produce 3 different numbers from 1 to 9 that correspond to the books selected. List each book on a separate piece of paper, place them all in a hat, and pick three.
What does it mean when sampling is done without replacement?
Once an individual is selected, the individual cannot be selected again.
