What is Melbourne Cup?

The Melbourne Cup is Australia’s most famous horse race held over a distance of 3200 meters at Flemington Racecourse in Melbourne. Held on the first Tuesday of November each year the ‘race that stops a nation is an opportunity to try and back a winner and claim bragging rights over your friends, workmates, and family. In this blog, I’ll show my process of creating a dashboard based on Melbourne Cup data.

 

Data Preparation – Web Scraping & Iteration Macro

I wanted to use the last 10 years’ data to do the analysis. But I found some websites’ URLs are different (2011-2019 & 2020-2021), so I need to do separate jobs in collecting the data.

 

a) Create an Iteration Macro to collect the data from 2011-2019

Figure 1. Iteration Macro for collecting data from 2011-2019

 

b) Create an Iteration Macro to collect the data from 2020-2021

c) Implement the Iteration Workflow

Data Wrangling

I got all the data. But some websites had missing values or dirty data. I need to do some data cleansing.

 

a) Data Cleansing for the two datasets and Union them

b) Create a Dataset about the trainers

The trainer column had some concatenated values. To fix that, I created another workflow.

Dashboard Creation

After getting all the data, put them in Tableau and create visualizations.

 

a) Make an introduction on my dashboard

b) Create the horse racing graph to show the moment of victory from 2011-2021

c) List the champion horses, jockeys, and trainers

d) Arrange the Layout and Finalise the Dashboard
