1 October 2019

What does a data analyst do?

 Data analysts work in a wide range of sectors, and across a large number of business units.  You find data analysts in marketing, finance, management, supply chain/procurement and markets as diverse as media, management consultancies, defence contractors, manufacturing, call centres and more.

But whatever market they are working in, and whichever business unit they are part of, the skills remain very similar.  A data analyst collects the data required (often from a variety of sources), reports it (via visualisation tools, Excel, etc) and analyses it.

From there they are able to produce not just the reports for senior management, but also provide analysis as to what has happened, what is happening and what could happen.  Vital tools to enable a business to make important decisions and to track their every day performance.

What skills are needed to be a data analyst? What are top 3 skills for data analyst?

Top 3 skills that you need to be Data Analyst:

  1. A mathematical mind set. Data is often represented in figures.  How these figures interact, how you can manipulate them, etc, is a key part of a data analyst’s job
  2. Communication skills. Both written and verbal. You will be reporting figures and providing analysis that may not make sense to someone without a data background.  You need to be able to create stories around what is happening, so that the average layperson would understand what they are looking at
  3. Computer skills. An important part of a data analyst’s job is being able to manipulate and visualise data.  Much of the manipulation is done using coding languages such as SQL, Python, R, etc and visualisation is often done using the likes of Tableau, Power BI, Excel and more.  Being able to quickly pick up various packages and computing languages is key
