Turning Data into information and information into Business Intelligence

Diploma in Data Analytics

Why Data Analysis?

Data is the lifeblood of many industries and understanding how to process, analyse and visualise that data is a skill much sought after by employers. The Diploma in Data Analytics is aimed at people who want to learn these skills and advance their career prospects. It’s also great if you work with data and want to boost your knowledge of analytics tools and processes to improve your overall productivity.

Course Overview

Data analysis is the process of evaluating datasets using statistical tools to reveal information you can make decisions with. Data analytics essentially examines large datasets to uncover not easily recognisable patterns, correlations, and other insights.

We’ll start by looking at the principles of the Data Analysis process, and the types of data you’ll be working with. Then we’ll examine the business aspects of analytics, the stakeholders and the Key Performance Indicators they use for decision making.

We then take a hands-on approach to guiding you through the tools that Data Analysts use every day; Excel, R, Python and Tableau, and how to apply these to real-world datasets and examples.
