Unfortunately, many managers falsely believe that sample size is:
A) related to proper data analysis.
B) related to the representativeness of the sample.
C) determined by computer programs.
D) an irrelevant "statistical" technicality issue.
E) related to the level of accuracy desired. - answerrelated to the representativeness of
the sample.
Which of the following statements is most accurate regarding the relationship between
sample size and the sample representativeness?
A) There is a high relationship between the size of a sample and the representativeness
of the population from which it is drawn.
B) There is no relation between the size of a sample and the representativeness of the
population from which it is drawn.
, C) You cannot have a representative sample unless the sample size is equal to or
exceeds 10 percent of the population.
D) Sample size determines representativeness but only if the sample plan is a
probability sampling plan.
E) Sample size determines representativeness but only if the sample plan is a
nonprobability sampling plan. - answerThere is no relation between the size of a sample
and the representativeness of the population from which it is drawn.
The sample size determines:
A) representativeness.
B) accuracy.
C) representativeness and accuracy.
D) the population statistic value.
E) the mean generated from the sample statistic. - answeraccuracy.
Sample accuracy refers to:
A) the extent to which the sample is validated.
B) the extent to which the sample statistics differ from the true population values the
statistics represent.
C) the extent to which the population statistics differ from the representativeness of the
sample.
D) a statistical concept that can be assessed only theoretically.
E) how close the sample statistics match the predetermined values expected by
management. - answerthe extent to which the sample statistics differ from the true
population values the statistics represent.
In a study of the U.S. workforce population, a research company interviews 5,000
persons on a street corner in New York. If they decide to increase the sample size to
10,000, they would:
A) increase the sample size and the representativeness of the sample.
B) increase both sample accuracy and representativeness of the sample.
C) increase only the representativeness.
D) decrease the sample accuracy.
E) increase the sample size, but the sample would still not be representative of the
population. - answerincrease the sample size, but the sample would still not be
representative of the population.
One of the reasons why a marketing practitioner should have a basic understanding of
sample size determination is because:
A) many practitioners have a false belief that sample size doesn't determine a sample's
representativeness.
B) it helps managers to manage their resources better.
C) a marketing manager should understand that a sample's representativeness is not
related to its accuracy.
D) the size of the sample is never a major cost factor.
