Walt Lewis was interested in knowing how best to allocate territories in Texas to the
new, 10-member sales force he hired. While the sales force was undergoing training,
Walt sought some secondary data that would help him allocate sets of counties to the
salespersons. He knew he had to be equitable and felt strongly that each set of counties
should have a market potential about equal to all the other sets. He needed some
quantifiable measure of the market potential for each county, and he didn’t want to use
any Census data because he felt like this was outdated. Which of the following sources
of secondary data would you recommend that Walt use?
A) Hire marketing research firm, Decision Analyst, Inc.
B) Seek an aggregator known for compiling local directory information.
C) Call the Office of Management and Budget (OMB) to access the most recent
Metropolitan SAs.
D) Call the Office of Management and Budget (OMB) to access the most recent
Micropolitan SAs.
E) Consult the most recent American Community Survey (ACS) in the geographic
region.
The only time the population size is important in the calculation of sample size is:
A) always; all formulas include N, a count of the total population.
B) when the population is very, very large.
C) when the population is not normal.
D) when the level of accuracy needs to be less than ±5 percent.
E) when the population is small, relative to the sample size.
