Some of the Valuable Skills that a Data Analyst Should Learn


SQL (Structured Query Language) is the industry-standard database language, and it is the most crucial skill in the data analyst job description. The language is frequently referred to as a “graduated” version of Excel because it can handle enormous datasets that Excel cannot.

Almost every company requires someone who knows SQL, whether it’s to manage and store data, connect different databases (like the ones Amazon uses to suggest things you might like,) or develop or update database architecture entirely.

2.Microsoft Excel

Excel is probably the first thing that springs to mind when you think of a spreadsheet, but it has a lot more analysis capability behind the hood. While a programming language like R or Python is better suited to dealing with massive data sets, advanced Excel approaches such as building macros and employing VBA lookups are still extensively utilized for more minor lifts and quick analytics. If you work for a small business or a startup, the first version of your database can be Excel.

3.Critical Thinking

To use data to answer your questions, you must first figure out what you want to ask, which might be difficult. To be successful as an analyst, you must think like one. A data analyst’s job is to find and synthesize relationships that aren’t always obvious. While critical thinking is intrinsic to some level, you may use a few strategies to increase your necessary thinking abilities.

4.Statistical Programming

R or Python can do what Excel does—and ten times faster. R and Python, like SQL, can manage what Excel can’t. They are statistical programming languages that can do advanced analysis and predictive analytics on large data sets. They’re also both industry-standard. To genuinely work as a data analyst, you’ll need to know at least one of these languages in addition to SQL.

5.Data Visualization

It’s critical to tell a compelling tale using data to convey your message and keep your audience engaged. You’ll have a tough time sending your message through to others if your findings can’t be immediately recognized. Owing to this, data visualization may make or break it when it comes to the impact of your data. Analysts convey their conclusions clearly and simply by using eye-catching, high-quality charts and graphs.

6.Presentation Skills

Data visualization and presenting abilities are inextricably linked. However, not every human is born with an ability to offer, and that’s fine! Even the most experienced presenters will occasionally let their anxieties get the best of them. Start with practice—and then repeat it more until you find your stride.

7.Machine Learning

Machine learning has been identified as a critical component of an analyst’s toolset, as artificial intelligence and predictive analytics are two of the trendiest subjects in the field of data science. While not every analyst works with machine learning, understanding the tools and ideas is essential for getting far in the profession. To advance in this field, you’ll need to have a firm grasp of statistical programming. Orange, an “out-of-the-box” solution, may also assist you in getting started with machine learning models.


Knowing what skills to learn and the data analyst job description and duties beforehand can be beneficial. You can be on the right track and succeed in your career efficiently.
