Data visualisation is the ability of persons how they can present the data findings via graphics or other illustrations. Individuals must have creative skills to visualise the data efficiently. The data-driven insights are easier to understand, even for those without expertise in data analysis. Data analysts can help decision-makers to identify patterns and understand complex ideas at a glance with data visualisation. This capability empowers data analysts to fill the gap between the organisation’s goals and customer needs.

  1. SQL

Structure Query Language is the common language used to communicate with data. Since the data analysts need to play with the data, learning SQL is a must.

  1. Python or R

Learning Python or R should be on the priority list to learn while planning to be a data analyst. These programming languages are ten times faster than excel and can handle the data more efficiently.

Python and R are powerful statistical programming languages used to perform advanced and predictive analyses of extensive data. An individual must master at least one of these languages to become a professional data analyst. You can master these skills by joining data analytics courses online.

  1. Critical Thinking

Analysing the data to extract valuable insights is critical as you first need to understand what you are trying to find from the data in the first place, which can be pretty tricky. You are planning to be a data analyst, but first, you need to start thinking like an analyst. The data analyst’s role is to discover and amalgamate the connections from raw data, which is not always clear. 

  1. Data Management

Data management is collecting, organising, and storing data efficiently and securely. With adequately managed data, even easy-to-use algorithms can generate remarkable insights. On the other hand, unorganised data can produce misleading insights and patterns that can affect business decisions.

  1. Communication

At last, you need to have strong communication skills to simply communicate the meaningful insights of the data in a simple form. You can’t be a professional data analyst if you don’t have strong communication skills. Being a good data analyst means being “bilingual.” You should be able to address highly technical points and provide clear, high-level explanations to ease a business’s decision-making process.
