SOLVED

21) Sampling a population in a geographical area using area sampling is a form of: A) systematic, geographic sampling. B) simple random sampling. C) nonprobability sampling. D) cluster sampling. E) geo-group sampling. 22) A sampling method that separates the population into different subgroups, and then samples all of these subgroups, is called: A) stratified sampling. B) area sampling. C) cluster sampling. D) simple sampling. E) comprehensive sampling. 23) If a population were not distributed symmetrically, you would use: A) simple random sampling. B) systematic sampling. C) cluster sampling. D) stratified sampling. E) unbalanced sampling. 24) The purpose of the weighted average in stratified sampling is: A) to provide an overall sample average that represents the true distribution of the population. B) to provide more weight to those strata whose averages are the lowest. C) to provide more weight to those strata whose averages are the highest. D) to provide an overall sample average that represents the majority of the strata. E) to provide more weight to those strata that are more important to society. 25) Which of the following would be most helpful in dividing the sample into different strata? A) a basis that will result in like responses across strata B) a basis that will result in different responses across strata C) a basis that is easy to identify D) a basis that uses some surrogate indicator of identification such as SIC/NAICS codes E) a basis that is the least expensive 26) One of the nonprobability methods used for sampling is: A) cluster sampling. B) systematic sampling. C) convenience sampling. D) stratified sampling. E) simple random sample. 27) An “educated guess” as to who should represent the population is required for: A) convenience samples. B) judment samples. C) quota samples. D) referral samples. E) hypothetical samples. 28) Snowball sampling is another name for: A) referral sampling. B) quota sampling. C) convenience sampling. D) rolling sampling. E) simple random sample. 29) When website visitors are selected at random and asked to participate in a survey, this is an example of: A) random online intercept sampling using simple random sampling. B) nonrandom intercept sampling. C) online panel sampling. D) random online intercept sampling using systematic sampling. E) simple random sampling. 30) If a random start is used in terms of visitors to a website, and then a skip interval is used to skip to the next visitor to ask to participate in a survey, this is an example of: A) random online intercept sampling using simple random sampling. B) online panel sampling. C) statistical efficiency in online sampling. D) random online intercept sampling using systematic sampling. E) skip online sampling.
