Develop a Strong Knowledge of Programming

The coding knowledge and experience required for a data analyst are not as high as that of a data scientist. However, you are expected to have the ability to explore and analyze large data sets. This is accomplished through data visualization tools such as Power BI and Tableau. However, not all companies can afford to buy these tools. So, the ubiquitous option is to use Python and its extensive data visualization libraries. Python is the best choice for anyone new to coding. You’ll get to manage with basic Python skills and master the key libraries required for this role, including Pandas, Matplotlib, Seaborn, Numpy, and Scikit Learn.

Basic knowledge of SQL – SQL is one of the most talked-about data analyst skills. Knowledge of SQL would give you control over accessing data from various sources. Understanding data recovery and integration will help you manage your data well.

Hands-on with Data Visualization Tools

Data analysts use data visualization tools on a very regular basis. Mastering these data visualization tools does not require technical knowledge. Most of these tools work by clicking and dragging. The important aspect is understanding the various functionalities required to analyze and visualize data using these tools. The more versatile your skillset is, the more likely you are to work on challenging, compelling, and business-transforming projects.

Become a Storyteller

The dashboard consisting of all the charts and data is not enough if it is simply colourful and pleasant to look at.

Thus, a business analyst must be able to convey a history of their findings without confusing the user. The story should be concise, simple, and accurately highlight the problem.

Learn Machine Learning

Machine learning enables organizations to gather greater insights from structured and unstructured data compared to what they could otherwise gather with traditional business intelligence solutions. In fact, it enables leaders to plan and take action. Applying machine learning and analytics more broadly enables you to respond faster to dynamic situations and get more value from those rapidly growing data treasures, making it an inevitable tool for data analysis.

Sharpen Your Analytical Skills

It is clear that analytical skills are the great importance for data analysts. These skills include gathering, classifying, and analyzing all kinds of particular raw data. Therefore, if you want to be a professional data analyst, you must expand your analytical skills and thinking. Analytical skills help you see a challenge or situation from different perspectives.

Acquire Domain Knowledge

Knowing the domain means understanding specifics about the industry and the particular company you work for. For example, if you work for a company with an online store, you may need to understand the nuances of e-commerce. Conversely, you may need to understand the systems and their functioning if you analyse data on mechanical systems.

Domain knowledge varies from industry to industry, so you may need to do your research and learn quickly. Regardless of where you work, if you don’t understand what you’re analyzing, it will be difficult to do it effectively, making domain knowledge a key data analyst skill.

Communication is the Key!
