Answer to Question 1

Stratified sampling subdivides the population into at least two different subpopulations (strata) and then draws a simple random sample from each stratum.

Systematic sampling divides the population size by the sample size and rounds the result down to the nearest whole number, m. Then, using a random-number table to obtain a number k between 1 and m, selects for the sample those members numbered k, k + m, k + 2m, and so on.

In cluster sampling, the population is divided into sections, then sections are randomly selected, and then all members of the randomly selected sections are surveyed. Examples will vary.

Answer to Question 2

B
