Selling Price Analysis for D.M. Pan National Real Estate Company

Introduction
With the real estate industry is growing fast and many investors are now considering
staking their money on this venture. With the increasing growth of big data, many Real estate
owners now considers to apply data to help them in pricing, and knowing the demands of people
and this helps them in making better decision especially in capturing the full needs of their
clients. To show the trends in the growth of day to day needs of people, price changes,
government taxation most of the real estate owners employees linear regression analysis which
when two variables of choice are compared and their relationship and pattern is determined, a
better understanding is derived from the analysis.
Thus, this report works to explicitly explain how the average median square feet affects
the average median listing price from a given random sample of 30 from a selected region from
the National Statistics data. A scatter plot is then used to show the relationship and pattern of the
variables and then gives the trend line and the regression equation which is then used to predict
the listing price of a certain house from a given square footage.
Representative Data Sample
East North Central was my region of choice, considering it had large stream of data
comparatively and that would give me a better representation of the entire data from the sample
size created. The random sample generated is presented in excel workbook as well as the mean,
median, and standard deviation of the median listing price and the median square foot variables.
Data Analysis
The average Median listing price which actually signifies the asking price of most of the
homes in East North Central Region is at $220,584 with an average of 1916 Median Square feet.
Comparing this metrics with the National Statics where all regions have an average of $288,408

and 1945 Median Listing Price and Median Square feet respectively. This implies that this region
is a true reflection of the national data and it’s statistically significant for conducting an analysis
for the overall data. The figures show that as the economy deteriorates, there is an increasingly
significant impact on the real estate industry from the regional level to the national at large.
Thus, as the economy continues to decline home and property buying also feel the impact.
The random sample used in this analysis is extremely random as I have generated it using
Microsoft excel from the data of the selected region (East North Central). The procedure applied
for generating the random sample include: first, adding a new column giving it a name
‘Random_Number’. Then in the first cell immediately after the column head, insert the function
“=RAND (); which when you press enter a random number is generated automatically. Copy this
generated random number from the first cell and paste it in the other cells in the same column to
generate other random numbers then after ensuring all the rows contains each random number,
finally sort all the records by Random_Number column. From that I chose the first 30 which then
became the random sample.

Median Square Feet
The Pattern
Scatter plots are very useful graphs for explaining the trends within the data. Each point
within the plot has two coordinates termed as x and y variables. In this case we use Median
Square Feet as the x-variable which is on the x-axis and Median Listing Price as the y-variable
which lies on the vertical axis.
The two variables x and y indicates a positive relationship as they tend to move from left
to right; implying that as the values on the x-axis increases, the y-values also increases; and that
leads to an Uphill pattern which is its shape. Outliers are points that are far from the trend line or
regression line. And in this case points [1954, $368,237] and [2712, $280,054] are considered to
be the main outliers. With a square footage of 2712, this home is considered outlier since it
attracts more money to buy and few can afford to get it and on the other hand features such as
desirable location or enhanced amenities like high advanced securities with CCTV’s installed,
swimming pools, more number of bedrooms and bathrooms leads to an increased money for

purchasing houses such as 1954 and that’s explains why it’s regarded as an outlier since its
listing price is at $368,237 which is a lot of money for average people.
The trend line equation, which is also the regression equation as shown in the scatter plot
is y=175.97x – 118809 where y is dependent variable (Median Listing Price) and x is the
predictor variable (Median square feet). Therefore if 1200 square foot house is given, it will be
listed at $92,355 because if you replace x in the equation with 1200 you get y = 175.97(1200) 118809 =92,355.
