ANSWERS TO APPLICATION QUESTIONS
13. The following data matrix has ten respondents. There are seven questions on the
survey (Q1–Q7). The possible answers for Q1–Q2 are “no” or “yes,” coded 0 and 1
respectively. Questions Q3–Q4 are answered with “none,” “somewhat,” “a fair

CASE SOLUTIONS
Case 10.1 IHOP Improvement Survey
Case Objective: This case requires students to understand the variable label, variable
description, value codes, and value labels aspects of the Define
Variables worksheet in the XL Data Analyst. Additionally, it tests if
they know how to add a new variable to an XL Data Analyst dataset as
per the recommendations in the chapter.
Answers to Case Questions
1. Indicate how Mary should set up the Define Variables worksheet in an XL Data
Analyst data set file.
The Variable Descriptions, Value Codes, and Value Labels are identified below. Two
tables are used, but these would continue horizontally in the worksheet. Note that
Media 2 and Media 7 are not listed due to space constraints.

2. Describe how Mary should create a new variable that is equal to the total number of
different advertising media where respondents recall seeing IHOP advertising.
She can create a new variable, say with the label Adtotal, as a new column to the right
of the Media 8 column on the Data worksheet. Then for each cell in this new column,
Mary can use the Excel function “= SUM ( )” or a simple summing formula
(= Media1 + Media2 … + Media8) to total the 8 Media cells for each respondent.

Answers to Case Questions
Keeping the quality of the data as a foremost concern, compare the practices of these two
competing panel companies, and recommend one that you think CMG research should
use for the Advanced Automobile Concepts survey. Why have you selected your choice
over the competitor?
The table is provided below with an “Analysis” row after each set of company responses.
Question 1. What experience does your company have with providing online samples
for market research?
Question 2. What are the people told when they are recruited?
Question 3. If the sample comes from a panel, what is your annual panel
turnover/attrition/retention rate?
Company A: Our voluntary drop-out rate is
Company B: We do a 1-for-1 replacement for each
Company B’s drop-out is low and its replacement system is superior to that of Company
A.
Question 4. What profile data is kept on panel members? For how many members is
this data collected and how often is this data updated?
Company A: We maintain extensive
individual-level data, in the form of about 1,000
Company B: For each panelist, we have about
2,500 data points on demographics, assortment of
It is obvious that Company B has more “stored” variables in their panel dataset. Plus,

Question 5. Explain how people are invited to take part in a survey.
Company A: Typically, a survey
Company B: Based on the client’s sample
The systems are almost identical except Company A’s reminder is daily while Company
B’s reminder is every other day.
Question 5. How does your company handle data quality issues?
Company A: Our panel members sign a statement
Company B: In all surveys with most questions,
we provide an option of “Refusal” or “Not
applicable,” where our panelists can indicate that
Company A uses an “honor” system, and does not indicate any data quality checking
system. So, there is the danger that its panel members will “forget” or otherwise not be
Assuming there are no other factors to consider (such as price), select Company B as it is
superior to Company A in five out of the six areas.
