Abstract


Problem and Motivation

Knowing sufficient information about resale flat prices, the trend, and the factors affecting the price is important for someone who wants to buy or sell a flat. Some of the key points that need to be answered includes the following:

  • What are the shares of the resale public housing supply in 2015?
  • What are the distribution of the resale public housing prices in 2015?
  • Compare the patterns of the first-half of 2016 with the patterns of 2015


Approaches

Data Preparation

The data can be obtained from https://data.gov.sg/dataset/resale-flat-prices. As we are more interested to analyze the resale flat price in 2015 and 2016, we will use the dataset from March 2012 onwards. After connecting the data to Tableau, we need to create a calculated field to transform the "Month" from text to date format. This can be done by using DATE(LEFT([Month],4)+"-"+RIGHT([Month],2)+"-01").

Data Analysis

The analysis done are mainly focused on comparing the patterns of 2015 with the patterns of the first-half of 2016.


Tools Utilized

Tableau is used for data preparation and analysis
