Turning Data into information and information into Business Intelligence

Diploma in Data Analytics

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.

There are many tools available to Data Scientists such as Microsoft Excel which is highly popular, R,  Python Data Analysis Libraries and Tableau for Data Visualization.

Excel is one of the most widely used tools for data analysis and indeed it’s built-in pivot tables are arguably the most popular analytic tool. It will be the base tool used throughout the course, but you will also get to work with R, Python and Tableau to achieve a broader appreciation of analytical capabilities.
