Subject Code : FIT5145
Assignment Task:

The aim of this assignment isto investigate and visualise data using various data science tools. It will test your ability to:

• Using R,
o read data files and extract related data from those files;
o wrangle and process data into the required formats;
o use various graphical and non-graphical tools to perform exploratory data
analysis and visualisation; and
• communicate your findings in your report.

Tasks:
• There are two tasks (A & B) in this assignment. Each task has separate data set files.
• You need to use R to complete the tasks.
• You need to use R Markdown to communicate
o your answers,
o the code you used to complete the tasks, and
o your explanation of the steps you took and any issues that arose

It is crucial that the R Markdown report you submit clearly identifies which questions you are answering, and explains how you are processing the data and why you are processing the data in that way. It is not adequate for you to just answer the questions for each task or just supply the code you used.

The data supplied for each task will also have to be wrangled in order to answer the questions. The supplied data is not guaranteed to be “clean” and without faults. This may require you to

• Examine the data,

• Filter the data,

• Deal with missing or inconsistent values or formats,

• Deal with any outliers or exceptional values,

• Merge or divide the values or data sets,

• Sort the data, and/or

• Any other pre-processing steps that are required in order to be able to analyse the data. Your report must explain why and how you are performing this data wrangling, including identifying any issues you find with the data.

Task A: Investigating the size of the Indigenous Australian Population

In this task, you are required to visualise the relationship between the distribution and age of Indigenous Australians and gain insights into relations and trends over time. The data files used in this task were originally downloaded from the Australian Bureau of Statistics (ABS). We have extracted the data from the original files and put it into a simpler format. Please download the data from Moodle:

• IndigAusPopData_by_region (Data1): This file contains yearly data regarding the estimated resident population of Indigenous Australians, grouping by indigenous regions, between 2016 to 2031.

• IndigAusPopData_by_state (Data2): This file contains yearly data regarding the estimated resident population of Indigenous Australians, grouping by state or territory, between 2006 and 2031.
