Essential Skills for a Data Analyst: Expectations of Employers

In today's data-driven world, the role of a data analyst is more critical than ever. A data analyst is responsible for turning raw data into actionable insights, and this requires a combination of analytical, technical, and communication skills. This article explores the key skills and expectations that most companies have for data analysts.

Core Analytical Skills and Comfort with Numbers

A strong foundation in analytical skills is requisite for any data analyst. This includes a solid understanding of statistics and the ability to handle mathematical tasks with ease. Data analysts must have a deep grasp of how to interpret data, manage complex calculations, and make meaningful inferences from the data at hand.

Vital Data Analysis Tools and Techniques

Proficiency in data analysis tools is another cornerstone of the data analyst role. SQL and Excel are the two most commonly required tools for this position. These tools enable analysts to extract, transform, and analyze data efficiently.

Visualization tools play a critical role in presenting data in a comprehensible and impactful manner. Data analysts should be comfortable using tools such as SAS Cognos, Tableau, and Python visualization libraries. These tools help in creating clear and informative reports that can guide decision-making processes within organizations.

Programming Languages for Data Analysts

Historically, the go-to programming languages for data analysts have been SAS and R. However, a 2019 survey by Burtchworks revealed a shift towards Python. As technology evolves, so do the expectations of employers. The survey highlighted that Python had surpassed SAS and R as the preferred language for data analysts. This change is partly attributed to the numerous libraries and frameworks available in Python that facilitate data analysis and manipulation, as well as its simplicity and readability.
