Which of the following statements is true?
a. Marketing research studies employing the exploratory strategy generally have as a
starting point an hypothesis specifying relationships between variables.
b. Trend analysis employing replicated cross'‘sections is more appropriate than
longitudinal analysis for studying brand switching behavior.
c. An advantage of the case or field study method over the field survey method is that

A researcher is interested in studying the effect of geographic location of grocery stores
on the prices they charge for various food items. A typical "market basket" is selected
and the researcher obtains data on the total basket price from 15 randomly selected
stores as shown below. Note that 5 of the stores were inner city stores, 5 suburban
stores and 5 campus stores.
Campus Inner City Suburban

problem is

Which of the following is FALSE?
a. A good test of a summary is self'‘sufficient in that a summary should not require the
appended full report but should be able to stand on its own.
b. In general, it is not desirable for the researcher to draw conclusions in the written
report. Rather they should limit their reports to presentation of the facts and should let
the reader draw his or her own inferences from this presentation.
c. The good summary in a research report contains the necessary introductory
information to provide background, and the important results and conclusions.
d. The true summary is an abstract of the whole report in which everything is restated in
condensed form.
e. As a general rule, the research report with wide distribution will require a more
extensive introduction than a report for a narrow audience since a major purpose of the
introduction is to provide the background information the reader needs to appreciate the
discussion in the body of the report.

increase with increases in the sample size.

surveys.
Which of the following statements about conjoint analysis is FALSE?

of the attribute.

be estimated.

simply choose which alternative in each pair they prefer.

ground in one day as it is with groups.

The principle which guides the framing of a null hypothesis is:

(determined by the a level) to the contrary
e. there is no guiding scientific principle and the analyst should frame them as he or she
sees fit
Which of the following is FALSE?

independent variables are manipulated by the experimenter under as carefully
controlled conditions as the situation will permit.
c. Laboratory experiments are distinguished from field experiments primarily in terms
of the degree of control over the variables, e.g. price, being manipulated.
d. The specially designed conditions of a laboratory experiment provide more control
than a field experiment.
e. They are all true.
Validity is
a. concerned with the relationships of random error with systematic error.

by examining the calculated value.
e. The contingency coefficient provides a measure of the strength of the association

Which of the following is true?
a. When sampling from a population that is highly skewed, a cluster sample generally
provides the most representative sample.
