learn how the dependent variable varies from subgroup to subgroup.
c. Cross tabulation is very useful for studying relationships between variables.
d. Although a variable is part of a planned cross tabulation, it is still necessary to
develop the one'‘way tabulation if one wishes to construct the histogram showing the
distribution of the variable.

page-pf3
a. quota
b. convenience
c. cluster
d. judgment
e. All of the above are nonprobability samples.
Which of the following about questionnaire design is TRUE?
a. Not including a "no opinion" category may force respondents to take a stand on an
issue on which they have no opinion. This can introduce response error.
b. Including an "other" alternative for a multiple-choice question frees the researcher
from having to make sure the list of alternatives is exhaustive.

approaches.
page-pf4
b. Multidimensional scaling analysis is typically used to refer to the attribute-based

d. a and b.
e. a, b, and c.
Which of the following is FALSE?
a. A Likert scale is an example of a comparative rating scale.
b. A semantic differential scale is an example of an itemized scale.

at the appropriate point on a line that runs from one extreme of the attribute to the other.
d. Itemized scales are similar to graphic scales in that individuals make their judgments
independently.
e. Comparative scales involve relative judgments.
Given a = prar = pnranr, where a is the overall mean and "r" refers to those responding
and "nr" to those not responding, which of the following statements is most correct?
a.Both ar and anr can be calculated by splitting up a (which is known or can be
page-pf5
estimated) into its component parts.
b.The nonresponse component can be ignored as it is reasonable that ar equals anr.
c.a cannot be calculated because of the difficulty in estimating ar and anr.
d.A rough estimate of a can be made by adjusting the initial results after a is estimated
by follow'‘up.
e.A rough estimate of a can be made by adjusting the initial results after anr is estimated
by follow'‘up.
An interviewer finds that a subject is not at home; to complete his sample, he
substitutes the nearest available subject for the missing subject. This practice

b. is not recommended as it complicates the problems by increasing the proportion of
at'‘homes in the sample.
c. is recommended even though it increases the proportion of at'‘homes.
d. is unreasonable although the results are generally accurate.
e. is probably the best available technique for handling the not'‘at'‘home problem.
Which of the following is TRUE?
a. The choice of a data-collection method for a specific issue reflects the firm's program
page-pf6
strategy.
b. A company's philosophy of how marketing research fits into its marketing plan
determines its project strategy for marketing research.
c. The design of the individual studies themselves defines the firm's program strategy to
research.
d. Project strategy should be dealt with before program strategy.
e. A program strategy specifies the types of studies to be conducted and for what
purposes.
A manufacturer is interested in selecting one of three companies to deliver (by truck) its
product to its distributors and wholesalers in a certain area. Each of the companies has
different operating procedures and uses different routes. Assuming that certain
minimum standards for delivery time are achieved, the manufacturer wants to select the
company with the lowest unit shipping cost.
In addition, the manufacturer believes that the type of packaging used for the product
may have an impact on shipping cost and is considering two types of packaging. It is
unknown whether or not any of the three companies under consideration is better
equipped to handle either type of packaging.
After using each of the companies for five deliveries of the product with each of the
types of packaging (thus, each company made a total of 10 deliveries, with all
deliveries under similar circumstances), the shipping costs per unit were calculated and
are shown below:

equal to the number of treatments.

d. The model underlying the randomized block design holds that the 8th observation on
the jth treatment results from the overall mean plus the treatment effect j plus the effect
of the ith block, plus random error.

A researcher is interested in comparing the usage of bank debit cards by consumers in
rural (r) and urban (u) areas. Each year for the past five years, she has surveyed 500
individuals (one'‘half urban, one'‘half rural) randomly selected from across the United
States. She is specifically interested in any differences that may exist between the two
groups with regard to usage. The results of the current study indicate that people in
urban areas use bank debit cards 12 times per month on average (xu), while those in
rural areas use bank cards 10 times per month on average (xr).
Given that the critical value that the test statistic is to be compared with is equal to
1.645 at a 90% significance level, which of the following statements are true?
a. The researcher should reject the null hypothesis at the 90% significance level.
b. The researcher might be able to reject the null hypothesis at the 95% level of
significance.
c. The researcher cannot reject the null hypothesis at this significance level.
d. The researcher has provided evidence that people in urban areas use bank debit cards
more than people in rural areas.
e. More information is needed before a decision about the null hypothesis can be made.
