UNSW School of Economics

ECON1203 Business and Economic Statistics

Session 1, 2016

Major project: Call of the Mall

Purpose

The idea is of this assignment is to simulate a professional work task involving statistical analysis. It is designed

to help students learn about what is involved in undertaking basic statistical analysis to understand a real-

world problem, and communicating the results of this analysis to business stakeholders.

Context and Problem

You are working as a business analyst for Your Market Consultants Australia (“YMCA”), a small Sydney-based

company that specializes in providing statistical consulting services to Australian companies seeking

intelligence about their present or potential customers. Your company is contacted by Eastfield, an owner of

several large shopping centres on the Australian Eastern seaboard. You are told that the marketing director at

one of Eastfield’s malls, Betsy Lu, is interested in using market research to inform leasing decisions (i.e.,

decisions about which stores to sign as tenants of shop spaces in the mall).

You attend a breakfast meeting with Ms Lu and a senior YMCA consultant to discuss her concerns in more

detail. At the meeting, Ms Lu says:

“So the situation is that we hired a market-research firm to come in and run an intercept survey* for us, which

they did, and the data were collected in a single week in October 2015. I’m now looking for someone with

statistical expertise to analyse the data and give us some recommendations.

The whole reason we did the survey is to find out what sort of shoppers we’re attracting to the centre, so we

have a better idea of what stores might do well in the mall. You see, the leases on about 30% of our tenants

are up at the end of next year, and we want to know which kind of companies to approach in order to fill those

vacancies. Some of our tenants have also struggled to pay their rent on time, which makes me wonder whether

they’re a good match to the centre.

Just based on casual observation, my sense is that our biggest shopper segment is high-income young women,

who stay at the mall for a long time and use their visits as social time with other young women, often with

babies in tow. I’d expect that at least 20% of our customers are high-income young women, though I’m happy

to be corrected on that. This would explain why our cafes and things like yogurt shops and Boost Juice type

places are generally doing well. We also seem to have a lot of teenagers in the after-school time slot – I’d

guess that they are our next-biggest shopper segment, though I’m not sure. We also have a community of

elderly people in the neighborhood, some of whom are regulars.

So, the first information I’m looking for is a breakdown of shopper types, both overall and by store type. I’d

also like to know whether we’re hitting Eastfield’s internal minimum threshold of at least $60 spent on average

per customer visit to the mall. Some information about the types of stores in which visits and spending are

clustered for our different shopper types would also be of use. Anything you can tell me about how to improve

our appeal to our main shopper types, of course, would be a great extra!”

Based on these comments, that afternoon you and the senior consultant draw up a consulting brief, which you

send to Ms Lu, who approves it and hires you to perform the analysis required to address her concerns. Ms Lu

then sends you an Excel file containing the data from the intercept survey.

You are given the responsibility of providing a statistical analysis of these data and for producing an associated

report that addresses Ms Lu’s concerns.

*intercept survey: a survey of shoppers leaving a shopping centre.

Report

It is natural to associate different parts of the project work with the coverage of relevant material in particular

Sharpe chapters and lectures. However, remember you are writing a professional report, not providing a

sequence of answers to assignment problems, so you should try to write a flowing report organized around

ideas, not methods.

The report should include a brief Executive Summary. Ms Lu, your audience, is an intelligent person but she is

not a statistician. Your Executive Summary needs to be non-technical so that she can assess what you have

done and understand your basic conclusions. The senior consultant at YMCA is familiar with technical analysis,

and will be reviewing the report before it is sent out to the client to ensure that the conclusions discussed in

the Executive Summary are reasonable and based on sound statistical analysis.

You can see from the marking rubric below that while your project mark will be based primarily on the

substance of your statistical work, the presentation of the material will also be considered. Reports should be

typed and should use appropriate graphical techniques to represent the data, as well as other appropriate

statistical analysis. For some guidance on what these types of reports might look like, please check the

“Project” section of the course website where some actual examples of statistical reports are posted.

As is the case in any actual work environment, there is no “one right way” to construct a report like this,

and hence there is no rigid template for what your project should look like, nor is there only one way to

approach the analysis.

Data

Each student will be assigned a personalized data set. Each individual data set refers to the problem above and

has the same structure. However, values of some of the key variables will vary across students, meaning that

statistical results and any inferences drawn from them may differ across students.

In the “Project” folder on the website, you will find an Excel file (“Project Data.xls”) that you will download in

order to obtain your personalized data set. Once you enter your zID into the highlighted cell in the Excel

worksheet, a personalized data set will be generated using which you should perform your analysis. Copy and

paste the generated data into a new Excel workbook, where you will conduct your analysis. Each data set

will contain a sample of 293 observations, where each observation refers to a separate survey response.

There are 13 variables, as follows:

pid = survey response identifier

visits = total number of stores visited on this visit

dayofweek = day identifier, taking values 1 (Monday) through 7 (Sunday)

freqmallvisit = responder’s estimate of his/her number of visits to this mall in the past three months

spend = responder’s estimated amount spent in mall stores, in total, on this visit (AUD$)

age = binary indicator of respondent’s age (assessed by interviewer), where

0=under 15

1=15-20

2 = 21-30

3 = 31-40

4 = 41-50

5 = 51-60

6 = 61 or over

HHinc = total household income of the respondent, where:

1=less than $40,000 per year;

2=$40,000-$80,000 per year;

3=$80,000-$120,000 per year;

4=$120,000-$160,000 per year;

5=$160,000-$200,000 per year;

6=$200,000 or more per year.

sex = binary indicator of respondent’s sex (assessed by interviewer), where

1=female

0=male

food = binary indicator where:

1=the respondent made a purchase at one or more specialty food/beverage stores on this visit

0=the respondent did not make a purchase at a specialty food/beverage store on this visit

apparel = binary indicator where:

1=the respondent made a purchase at one or more specialty apparel stores on this visit

0=the respondent did not make a purchase at a specialty apparel store on this visit

department= binary indicator where:

1=the respondent made a purchase at one or more department stores on this visit

0=the respondent did not make a purchase at a department store on this visit

grocery= binary indicator where:

1=the respondent made a purchase at one or more grocery stores on this visit

0=the respondent did not make a purchase at a grocery store on this visit

other= binary indicator where:

1=the respondent made a purchase at one or more other types of stores on this visit

0=the respondent did not make a purchase at another type of store on this visit

Tutorial work

You should think about the problem and plan what needs to be done before you actually start undertaking

extensive computing work. In order to assist in this process, there will be some project discussion time in

tutorials. In particular, in your Week 7 workshop you will be asked to review the problem and to discuss with

other students what is required by way of analysis. You should generate your data, and then copy, paste, and

save it into a new Excel workbook that you bring along to class as part of your preparation for your Week 7

workshop. In this Excel workbook, you should take time before class to generate some descriptive statistics for

your data that you can show your tutor in Week 7. This will confirm that you have correctly created your data

set and that you are ready to commence your analysis. These descriptive statistics will also be required to

answer a Week 7 workshop question.

In your Week 9 workshop, time will be devoted to monitoring your progress and discussing how more recently

covered material might be relevant to the project tasks. Naturally you should consult your tutor or lecturer

should you have any other questions regarding the project.
