This course will provide you with an overview of the entire data visualisation process in addition to introducing important development constructs and methodologies while using Power BI as a focal point. As this is an introductory course, no pre-requisite qualifications are necessary, but any experience in Computing and particularly in data visualisation is advantageous.
This course is designed to meet the needs of candidates who are currently working in related fields and may want to up-skill or for those who wish to pursue entry-level roles in the ICT sector. This course is also ideal for those who wish to pursue further study in Computer Science.

Why Data Visualisation?

Data has been called the new oil because it is a business asset and has a value, but in reality, data is the new sunlight. Unlike oil, data can be used over and over again, to keep driving insight and keep delivering value.

All organisations today are increasingly becoming data driven, the ability to work with data isn’t a bonus it’s essential. Data visualisation is about becoming a story teller presenting key insights in a form that is easy to understand. It is a unique mixture of art and science delivering impactful, insightful and digestible data visualisations. This requires balancing phycological design principles & colour theory, with engineering a suitable data set and analysing the data accurately.

Power BI was chosen as the tool to deliver this module. Microsoft Power BI is a fantastic tool that can handle all of the analytical pipeline from ingesting and modelling data to presenting it as a dashboard and distributing those dashboards to anyone who cares. Because of its potential as a complete data Pipeline, Microsoft Power BI is fast becoming one of the most used tools on the market.

Introduction to Power BI
• How to download and install Power BI
• How to import data into Power BI
• How to transform Data within Power BI
• How to create data visualisations with Power BI

Data visualisation pre-processing techniques
• Learn data cleaning techniques relevant to data visualisation – data aggregation, data sampling, impute missing data, find inconsistencies.
• Learn transformation techniques – data normalisation, construct new variables, investigate how to use regular expressions and data manipulation techniques to pre-process data sets.

Data Analysis
• Learn how to interrogate data
• Learn creating calculations and formulae to drive insights

Data Visualisation traditional statistical approaches
• Histograms, boxplots, scatter plots
• Analysing correlations and patterns between variables
• Univariate, bivariate and multivariate ways of presenting data

Advanced visualisation techniques
• Investigate computer-based tools for visualisation and their features – interactivity, geospatial methods, hierarchical and networks solutions.

Visual Analytics
• Understand and critique the various visualisation methods used to solve data mining and data analytics problems, e.g., anomaly detection, pattern discovery.

Data Analytics Techniques
• Investigate the main pitfalls in data visualisation and data analytics in a realworld setting.
• Compare and contrast data analytics techniques investigating their theoretical principles, assumptions, strengths and weaknesses.

A pass grade on the written assignment will be required for awarding the Professional Diploma.
Similarly, the Project must be handed in on the due date unless a sound reason for lateness is provided. In such instances, an extension may be awarded at the discretion of the lecturer.
