Role
You are working as a Data Analyst at BIA Solutions. Below is a list of 18 datasets provided to BIA by various clients for analysis. As a member of the analytics team, your task is to select one dataset and begin working on its analysis.
Data Visualisation Requirements
You are required to use Python to create six data visualisations based on the dataset you have selected. Your visualisations should help present important patterns, trends, and relationships in the data in a clear and meaningful way.
Your six visualisations must include the following:
Two simple visualisations showing one piece of information only.
Two comparison visualisations showing differences between two or more groups.
One heatmap to show relationships, patterns, or correlation in the data.
One advanced visualisation created using the Seaborn library.
You must also:
explain each visualisation clearly
analyse what the graph shows
describe what the data is suggesting
comment on any important pattern, trend, difference, or relationship shown in the graph
In other words, you must not only present the charts, but also show that you understand what they mean.
Task
Writing a research paper
Chapters will consist of the following sections.
Introduction:
Define and explain the concept of big data.
Explore the fundamentals of big data.
Investigate the value of data for decision-making processes for both end users and organizations.
Analyse the advantages and challenges of data-driven decision-making within an organization.
Evaluate the potential impact of using data for decision-making on both users and organizations.
Techniques:
Outline statistical and graphical techniques commonly applied for big data and visualization in the industry.
Review industry-leading tools and software solutions available for analysing and visualizing data.
Compare the usage of different industry-leading tools and software solutions for data analysis and visualization, providing examples.
Methodology:
Provide a detailed explanation of the dataset you have selected for analysis.
Describe the tools and techniques utilized to work with the dataset.
Present and interpret the findings derived from the dataset.
Evaluate your data preparation and manipulation process, justifying your choice of statistical techniques and explaining how these meet the needs of stakeholders for the given dataset.
Discussion:
Discuss the various roles, responsibilities, and challenges faced by data specialists.
Review strategies employed by data specialists to ensure compliance with data regulations and standards.
Conclusion:
Examine the roles, responsibilities, and challenges that data specialists encounter when integrating ethical principles into a data-driven culture.
