Data Analysis Assignment:
Question 1 -Statistical Inference:
Your relative or friend asks you if house prices are usually higher than unit/apartment
prices.Use Price $000 and Type data and an appropriate statistical inference technique to
answer the following question:
On average in town/city are house prices higher than unit/apartment prices?
Replace town/city with the name of the particular town or city of your sample.Delete apartment for samples 0, 1, 2, 3, 8, 9
Question 2 -Simple Linear Regression model:
Your friend or relative asks you how the number of bedrooms a property has influences
the price.Use Bedrooms (independent variable) and Price $000 (dependent variable) to model
the relationship between number of bedrooms and price.
Explore this relationship by
1. Plotting data with a scatter plot.
2. Calculating the least squares regression line, correlation coefficient and coefficient
of determination.
Question 3 -Multiple Linear Regression model:
Your relative or friend now wants to know what other factors may have an influence
on price.
Explore this by adding Bathrooms, Garage/Car and Type as additional independent
variables to the regression model developed in Question 2 and
a) Calculating the multiple regression equation, multiple correlation coefficient, and
coefficient of multiple determination.
b) Using appropriate tests to determine which independent variables make a
significant contribution to the regression model.
Hence, determine which independent variables to include in your model.
