Question 1

Periodicity occurs in which type of sampling design?

Accepted Answer

A)   simple random
B)   systematic random
C)   stratified random
D)   multistage cluster B

Question 2

Describe how you would select a sample of students from your college, using random sampling techniques. What are the benefits of your technique? What are the challenges?

Accepted Answer

Answers may vary. Random sampling-a method of sampling that relies on a random, or chance, selection method so that every element of the sampling frame has a known probability of being selected; begin with a sampling frame, perhaps a directory that lists all the names of students at the college; then by using a computer program of a random number generator, select a number and go down the list starting from the top and pick every nth person to be selected for the study; make sure the names are not in alphabetical order. Students should address how random sampling impacts research design and quality. May address issues of generalizability and validity. Students may discuss the difficulties of obtaining a sample, avoiding error, etc. in their analysis of challenges.
