YearBuilt Year the house was built
CouncilArea Governing council for the area
Lattitude Latitude

Given that there are two variables for the number of rooms (Rooms and Bedroom2), please use
Rooms in the analysis and ignore Bedroom2.
You got a client who would like to better understand real estate market and purchase the
property. Your tasks are listed below.
Task #1: Market conditions (7 points)
Your client would like to know more about the market conditions about the real estate market
in Melbourne (including all subu
s). Please provide the time series graphs for quarterly sale
volume (the number of sold properties) as well as mean and median sold price for the 2016-
2018 period.
Has the average property price increased in the first quarter of 2018 compared to the last quarter
of 2017?
Have the mean and median property price increased in the first quarter of 2018 compared to
the first quarter of 2017? Which measure (mean or median) is more suitable to use to describe
the property price evolution?
Discuss the results, including the limitations of the tests.
Task #2: Descriptive statistics (7 points)
iefly your sample, including the number of observations, outliers. Provide the
descriptive statistics of the sample. How you choose to do this is entirely at your discretion.
However, it is recommended that you consider using both summary statistic and graphical
methods while also noting any peculiarities within the data set. In addition, your client would
like to see:
 the histogram of the sold price for the entire sample1
 and the histograms of sold price for the year 2016 and the year 2017 on the same figure.
Task #3: Property price estimation (13 points)
Your client would like to purchase the following property:
 Subu
: Balwyn North
 Distance: 9.2
 Rooms: 4
 Type: House
 Car: 2
 Bathroom: 3
 Landsize: 700
 BuildingArea: 220.
You are expected to build a regression model of house prices. In doing so, make sure that you
use an appropriate number of predictors to develop your estimates. Once you have constructed
an appropriate model, use it to obtain:
 A point prediction of the expected property price

1 You may refer to the textbook on how to determine the optimal bin width.
 A 90% interval prediction for this price.
Discuss the significance of the independent variables in your model. Suppose your client is
flexible and he can drop the requirement for house are to be 220 sq. meters. Please compute:
 A point prediction of the expected property price
 A 90% interval prediction for this price.
Compare the obtained results with the previous findings.
Your client’s friend is a builder, and he told your client that it is possible to extend a 3-bedroom
house to a 4-bedroom house for $150,000. Would you recommend your client to buy a 3-
edroom house and then renovate it rather than to buy a 4-bedroom house (assuming that after
enovation the 3-bedroom house will become equivalent to a 4-bedroom house)?
Your client expects that property price increases with the number of rooms (controlling for
many other factors) and would like to know whether this positive relation is impacted by the
number of bathrooms.
Task #4: Hypothesis testing (7 points)
You client hear that property prices in Brighton are higher than in Balwyn North. Develop the
appropriate hypotheses and test them using t-test and regression analysis. Discuss the results.
Task #5: Buying property (9 points)
Your client would like to know whether property price depends on the sale method. Would you
ecommend your client to purchase property prior to the auction, or in the auction, or after the
auction, given the empirical data?
Your client has been told that large real estate agencies are able to sell properties at higher
prices. You are asked to check this statement. Assume the following agent types:
 big (market share over the sample period in terms of number of sold properties >= 6%)
 medium (1% <= market share over the sample period in terms of number of sold
properties < 6%), and
 small (market share over the sample period in terms of number of sold properties <
Would you recommend your client to take into account the agent type when buying the
Task #6: Limitations of the analysis (7 points)
Discuss the limitations of the analysis and how they affect your recommendations to your
Additional information
Our sample is likely to contain missing values, outliers and be subject to other imperfections.
You may need to consider them prior to starting the analysis. Further, the sample includes
properties that were not sold. You should drop those observations.
To ensure that regression residuals “behave well,” you may need to scale or transform one or
more variables. For example, to use a natural logarithm value of the variable instead of its raw
Good luck!

The table shows the mean and median of price of house in Austrialia (in dollars) for each quarter. It’s is found that quarter-4 in 2016 has the highest mean pricing of $10946544.66, followed by quarter-2 in 2017, mean pricing of $1080965.33.
Comparing the last quarter of 2017 with first quarter of 2018, there was reduction in the mean property price, it shows that there is decrease in property value when compared to quarter-1 of 2018 with quarter-4 of 2017.
    * P-value
Here we used unpaired t-test to compare mean property pricing of first quarter between 2018 and 2017. There was statistically significant difference noted between 2018 and 2017.

    House Type
    Town house
    Grand Total
Overall population consists of 68.8% of house, whereas 20.1% has town house and remaining Unit type of house.
    Sale Method
    Grand Total
It is noted that, more than half of the property were sold in auction its about 56%, followed by property sold in prior and property passed was about 14% respectively.
    Region Name
    Average of Price
    Min of Price
    Max of Price
    Eastern Metropolitan
    Eastern Victoria
    Northern Metropolitan
    Northern Victoria
    South-Eastern Metropolitan
    Southern Metropolitan
    Western Metropolitan
    Western Victoria
    Grand Total
Based on the region wise segregation, Southern metropolitan has the highest average pricing property with $1395928.33, followed by eastern metropolitan and southern eastern metropolitian.

Regression Output:
The model.1 is run with explanatory variable(Rooms, Type, Distance, Bathroom, Car, Landsize and Building area. Before running the analysis the Type variable is recoded as following, H-1, U-2 and T-3. the above table says that there is a strong negative relationship between type and positive relationship between rooms, distance, car, bathroom, Landsize and building area. There was a statistically significance difference noted between all explanatory variables except car and landsize. Based on the test of significance and adjusted R-squared value it is found that above model does not fit the dependent variable, seem to be a poor model with adj-R square (0.4548).
The fitted equation of the best model is:
 Price= -3059660+ 179728.2*room - 293287*type + 456099.9*Distance + 103062.7*Bathroom + 7536.317*Car +7.4150*Land size + 1002.86*Building Area
· Null hypotesis: property pricing of Brighton are not higher than Balwyn North
· Alternative hypothesis: property pricing of Brighton are higher than in Balwyn North
    Balwayn North
There was statistically significant difference between Brighton and Balwayn North.Since the p-value is less than 0.05, and, hence we reject our null hypothesis. Hence, it is concluded that property pricing of Brighton are higher than in Balwyn North.
