    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
    3
    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.
    4
    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.
    Details
    Length:  No longer than 1200 words, excluding tables and graphs. Total length including
    all discussion, tables and graphs should not exceed 8 pages.
    Cover sheet:  Attach the project assessment sheet (given below) as your first page. Check
    that you have completed the top (grey) sections in full, including your
    signature. Do not use plastic sheets or binders. Simply attach the completed
    cover sheet and staple the pages together.
    Project mark:  The project will be marked out of 20, and will constitute 20% of your total
    course mark.
    Due date:  A hard copy of your assignment is to be submitted to your tutor in or before
    your scheduled workshop in week 11 (beginning May 16). In addition to the
    hard copy, you must also submit an electronic copy to the course website by
    6 pm on Friday May 20. Upload your assignment via the Turnitin link on the
    course website. Browse and upload a copy of your document - do not paste
    text. Use your student zID in the file name (e.g., z1234567.doc).
    Late submission:  20% of the value of the project will be deducted for every day or part thereof
    that the hard copy is turned in after the start time of your Week 11 workshop
    (including the weekend). Projects submitted more than five days late will not
    be marked and will be assigned a mark of zero. You can and should be working
    on the material regularly before the due date. Extensions will only be granted
    in exceptional circumstances and must be approved by the lecturer-in-charge.
    For more details about late submission, see the Course Outline.
    Plagiarism:  While you are encouraged to discuss the project with other students, each
    person must submit an individual assignment that represents his or her own
    work. All assignments will be checked for plagiarism on the Turnitin software
    into which they are uploaded. The software will automatically check against all
    other projects ever submitted. Material copied from previous projects will be
    found and the source will be identified. Evidence of plagiarism will be treated
    extremely seriously: automatic and immediate failure in the course is a
    possible penalty. See Part B of the course outline for further details about
    UNSW’s policies on plagiarism. If you are in doubt about how to identify or
    avoid plagiarism, follow the link to and complete the self-paced Working with
    Academic Integrity module on Moodle.
    Coverage:  In your work for this project, you are only expected to use the statistical
    techniques developed in the text and lectures up until the end of week 9.
