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?
(28) VerifiedAnswers 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.
Conducting a census of the entire population of interest can eliminate the issue of generalizability.

Quota sampling is a nonprobability method intended to overcome a flaw of availability sampling in which the sample will just consist of whoever or whatever is available.
(35) People who are selected but do not participate in a study are referred to as ______.
(37) Dr. Wong is studying the frequency of binge drinking on a college. She interviews a sample of students about their alcohol consumption and generalizes the results. What is the target population for her study?
(30) What is the logic of inferential statistics? Why are inferential statistics relevant for social research?
(28) Simple random sampling, stratified random sampling, cluster sampling, and systematic random sampling are the four most common methods for drawing random samples.
(41) In social research, what is the importance of sampling? When is sampling unnecessary?
(37) When a sample has an underrepresentation of certain population characteristics because of the method used to select the sample, this is known as ______.
(37) When you study an entire population of interest, rather than drawing a sample, you are conducting a ______.
(38) ______ sampling methods rely on random selection procedures, such as flipping a coin.
(32) If all the elements that would be sampled are identical, sampling would be unnecessary.
(30) Using known information known about a total population before sampling is known as ______.
(29) Sample generalizability depends on the amount of sampling error in order to determine the quality of the sample.
