PREPARE A DATA ANALYSIS REPORT ABOUT YOUR WORK AND EXPLAIN YOUR FINDINGS

Assignment Task

You are a member of the team, and need to perform data analysis on countries in the region of East Asia & Pacific.

The team has not set any specific goal for the analysis. Therefore, you have the freedom to explore the data, and dig out anything you feel interesting or significant.

You have been requested to prepare a data analysis report about your work and explain your findings. The potential audiences include other researchers, business representatives, and government agencies. They may have limited ICT or mathematical knowledge.

To prepare the report, please follow the following outline:

1. Introduction

Provide an introduction to the problem. Include background material as appropriate: who

cares about this problem, what impact it has, where does the data come from.

2. Data Setup

Describe how to load the data, and the libraries needed. Provide an overview of the data

about its dimensions and structures.

3. Exploratory Data Analysis

Perform 3 one-variable analysis. Plot at least one graph for each variable. Explain why the

selected graph is appropriate.

Perform 2 two-variable analysis. Plot at least one graph for each variable. Explain why the selected graph is appropriate

The analysis can be performed on all years and all countries, or on a subset of your interest.

4. Advanced Analysis

4.1 Clustering

Briefly explain the concept of clustering and k-means.

Try to do a clustering analysis to group countries according to some selected attributes.

4.2 Linear Regression

Briefly explain the concept of linear regression.

Try to do 2 linear regression analysis. Plot the learned models.

The analysis can be performed on all years and all countries, or on a subset of your interest.

5. Conclusion

6. Reflections

In this part, discuss any difficulties you had performing the analysis and how you solved

those difficulties. Reflect on how the analysis process went for you, what you learnt, and what you might do differently next time.

For the data analysis, you need to provide both R code, and the explanation to the code and the result. For the section 2 – 4, please represent each R code snippet in a box with some comments. For example:

# Draw a boxplot on the attribute “Income”

boxplot(MyData$income)
