Question #2
Which of the following statements is true of the sample size for nonprobability samples?

B.   The sample size formula must be adjusted for confidence level before it can be used for nonprobability samples.
C.   Determining the sample size for nonprobability samples is usually a subjective, intuitive judgment made by the researcher.
D.   Determining the sample size for nonprobability samples requires the researcher to make statistical inferences about the true population parameters.
E.   The sample size formula must be adjusted for population variance before it can be used for nonprobability samples.

B.   cluster sampling.
C.   census sampling.
D.   area sampling.
E.   quota sampling.
Question #10
