A business intelligence analyst uses data to offer an understanding of a firm’s performance so that it can make healthier business choices.

Data Analysts

Role and Key Responsibilities:

Data analysts collect, process, and blend data from different sources to identify trends and patterns, then create visualisations and reports for stakeholders.

What Does a Data Scientist Do?

Collecting and Processing Large Datasets

Taking data gathered from different inputs and ensuring that it is ready for analysis is a key task for data scientists.

Building and Validating Predictive Models

They train and implement predictive models to make predictions of outcomes and to spot patterns in the data.

Analysing Data to Identify Trends and Insights

Data scientists analyse data to uncover trends and insights that can inform business decisions.

Creating Data Visualisations and Reports

They turn their conclusions into graphs and written reports for their insights to be clear and actionable.

Communicating Findings to Stakeholders
