Objectives
In this assignment you are expected to develop and present a business report to the senior
manager of a real estate company. The report should be informative but concise. It should
follow a specific structure to allow the document to be easily read and understood. For this
writing available on e-tivity 5.3 before you start the assignment. This assignment is worth 20% of
This assignment provides students with opportunity to:
• combine statistical analysis and report writing skills to prepare a concise and non-
• draw a random sample to complete statistical analysis,
• develop and enhance computing skills, specifically the use of MS Word and MS Excel
built-in functions,
• apply statistical techniques to a data set, and
• reinforce taught concepts including descriptive statistics, sampling and estimation,
hypothesis testing, correlation and regression.
Background
Margaret is the manager of a real estate company. She is concerned about the recent rising trend
of house prices and would like to further investigate the current market conditions. She would
also like to know whether the common assumptions in the property market are still valid. For
that purpose, Margaret asked Jason, a newly appointed research officer, to conduct a number of
statistical tests (discussed in the following sections) using a dataset related to the total number of
property purchased in three states of New South Wales, Victoria and Queensland in the first
week of September 2015.
The excel file that contains these data is named FIN60003_Assingment Data.xls and is available
on e-tivity 7.5. There are seven variables and 1000 cases in this data set. They are:
GENDER: Gender of property buyers (F: Females and M: Males)
AGE: Age of the property buyers in years
STATE: Location of property (NSW: New South Wales, Vic: Victoria and Qld: Queensland)
LAND SIZE: Property land size (in square meters)
NO of ROOMS: Number of rooms in the property
PRICE: Total purchase price in whole dollars
SALE TYPE: (1: Auction and 0: Private Sale)
You are going to help Jason in developing a report that addresses Margaret’s concerns. Since
Margaret is not very familiar with statistical terms try to not just quote statistics or analysis
FIN60003 Assignment Page 2
results, but explain what they mean. In general, do not include in the report formulae,
calculations, definitions of statistical terms or discussions on how graphs are constructed. Where
appropriate these may be included in the appendices. Follow the Harvard Style Guide (available
on e-tivity 5.3) for all in text references, reference lists and bibliographies.
It is important to properly analyse, discuss and interpret the results of your calculations. A
written description of the key features of the tables and graphs should be presented as well. The
emphasis will be on interpretation and analysis, not just the computation of statistics and
construction of graphs. The assessment should be in one single Microsoft Word compatible
document and should be written in 12 point font. It is expected that all work submitted, will
have been edited for spelling, grammar and clarity.
Most of your statistical calculations should be carried out using Excel only. You will use
Microsoft Word and Excel to complete this assignment.
1.  Select a Random Sample
Select a random sample of size 100 from the given 1000 cases (assume this data set is the
population of interest and you are not allowed to calculate any parameters such as mean and
standard deviation). You will use this sample data to complete tasks 2 to 6. Since repeat cases
may occur when you draw random numbers and each case can be included only once in your
sample, some of you may end up with a sample size less than 100. In this situation do not draw
another sample to reach 100 values. You will continue to work on your originally drawn sample,
even if the sample is smaller than 100.
2.  Descriptive Statistics
Use appropriate data summary methods to describe each of the variables in your dataset. Use an
appropriate graphical and/or summary statistical technique, chosen according to the type of
variable. These techniques will be chosen from:
Tabular Techniques:  Frequency tables and Grouped (joint) frequency tables.
Graphical Techniques: Pie chart, Bar graph, Histogram (avoid using 3D effects).
Summary Statistics:  Mode, Median, Mean, Standard Deviation, Range, Coefficient of
Variation and Interquartile Range.
You will need to choose the most appropriate technique(s) for each variable being analysed. Less
appropriate/inappropriate techniques will receive fewer/no marks.
For a nominal or an ordinal variable draw a graph and present a frequency table in percentages.
For a ratio or an interval variable draw a graph and a summary statistics table.
FIN60003 Assignment Page 3
Try to use varying visualisation techniques such as pie chart, bar chart, and histograms in
drawing graphs. Do not draw two different graphs for the same variable.
3.  Confidence intervals
Estimate the following quantities, using 95% confidence level. Interpret the meaning of your
confidence intervals.
i.  The average age of property buyers for the AUCTION sales only.
ii.  The average total purchase price for all types of sales.
Compare both intervals with their respective true population means.
4.  Hypothesis Testing
Margaret has some assumptions about the property market and wants to check their validity in
the new market conditions. Investigate these contentions by carrying out appropriate hypothesis
tests.
i.  It is often felt that female property buyers spend less on average than male property
buyers. To test relevant hypothesis only consider AUCTION sales.
ii.  It is often felt that the average property prices differs for New South Wales and two
other states (consider Vic and Qld as one sample). For this hypothesis use STATE.
iii.  It is often felt that the average number of rooms for properties in Victoria is more than
those for properties in New South Wales.
In the main section of the report, only include the non-technical explanations of your
methodology and findings. The immediate calculations and excel outputs should be presented in
an appendix. Use 95% confidence level.
5.  Correlation and Regression
In this section, first, Jason intends to investigate the relationship between the property price and
age of the property buyers for AUCTION sales only. As the second test, he investigates the
relationship between the property price and land size.
Use these variables to develop two separate regression models and explore the relationship
between average property prices on the one hand, and age of buyers and the land size on the
other. Make sure that you undertake full regression analyses, with appropriate discussions for
• a scattergram coupled with a brief description of the output
• an estimate of the linear regression model
• the coefficients of correlation and the coefficients of determination
• test results of a hypothesis for whether or not there is a linear relationship between
dependent and independent variables.

Assignment structure:
Presentation is an important feature of a business report. The guide to presentation that follows
includes an Executive summary, Introduction, Analysis and Appendices (please refer to the
instructions given in e-tivity 5.3). Your assignment should contain the following sections:
Executive summary
This is your first page and not to be included in the page count. Executive summary should be a
combined form of Introduction and Conclusions.
• Report only the highlights of the findings
• Entice an Executive to read on
• Essentially a lively summary of the main conclusions
• It should be no longer than one page and it must be on a separate page from the rest of
the report.
Introduction
This should contain information about what we expect to read in the project.
• State the purpose of the report, e.g. what you will discuss in the report
• Outline the report structure
• Provide a brief description of the methodology and the software used in analysis
• Describe the source of the data
THIS SHOULD TAKE ABOUT HALF A PAGE.
Analysis
This section contains a thorough yet non-technical description of all the findings (graphs and
tables will be included only where they help this discussion). It details the results that were
highlighted in the Executive Summary. No calculation is required here but appropriate graphs
and tables should be included. Your analysis section should contain the following sub-sections:
• DESCRIPTIVE STATISTICS
There are 7 variables in your data sets. Depending on the level of measurement (Nominal,
Ordinal or Interval/Ratio measure) you will need to provide an appropriate graph, a summary
statistics table and interpretations related to each variable. Take one variable at a time.
THIS SHOULD TAKE ABOUT TWO PAGES.
• CONFIDENCE INTERVAL
“We are 95% confident that………….”
Do not show the method of calculating a confidence interval (Calculation details should be
reported in appendices). Do not draw a graph. THIS WILL TAKE HALF A PAGE OR LESS.
FIN60003 Assignment Page 5
• HYPOTHESIS TESTING
Do not write H 0 , H A etc. Only your interpretation of results such as “hypothesis test was
performed on………” Also report the type of hypothesis (i.e., upper, lower, two-tail), the test
statistic, p-value, and degrees of freedom. Report the sample data used for analysis of this section
in the appendix. THIS WILL TAKE AROUND ONE PAGE OR LESS.
• CORRELATION and REGRESSION
Present your scatter plots with a line of best fit included in the graphs. Clearly specify the
dependent and independent variables and describe the strength of relationships using R and R
squared values.
Interpret the slope and intercept coefficients as well as hypothesis test result (t-value, p-value,
etc.). Report the sample data used for analysis of this section in the appendix. THIS WILL
TAKE ABOUT ONE AND HALF PAGES OR LESS.
Conclusion and limitations
All the important findings and results of your work should be presented here in a concise
format. Do not include any tables or graphs. This section is
• Essentially an expansion of the Executive Summary written from the point of view that
the Executive Summary has not been read.
• It ends with a discussion of the limitations of your analysis.
THIS WILL TAKE HALF A PAGE

.
Reference list
Follow the Harvard Style Guide (available on e-tivity 5.3) for all in text references, reference lists
and bibliographies (reference list and appendices are not included in the page count).
Appendices
• Each appendix must be numbered and be referred to in the main body of the report (if
possible print double-sided).
• Must contain your selection of random numbers and related random data and any
additional calculations and computer outputs (do not print the entire population).
• Also attach your EXCEL outputs for descriptive statistics, confidence intervals,
hypothesis testing, and regression analyses.
Graphs must be presented in the main body along with relevant tables and discussion. Those
Graphs that are presented in the appendices only will not be marked. Only include relevant
Excel outputs in the report, and place the rest of outputs in the appendices. However, try to
keep the appendices to a moderate size. Remember that examination is entirely based on the
FIN60003 Assignment Page 6
report itself and any excel outputs appeared in appendices are only to confirm your excel
calculations.
Instructions above about the page lengths are only a guideline. You will not be penalized for
changing these, as long as your report remains within the 6-page limit.
