Organizations in all fields rely increasingly on data to make critical business decisions like what products to make, which markets to enter, what investments to make, and which customers to target. They also use data to find areas of the business that are weak and need to be fixed.
Because of this, data analysis has become one of the most sought-after jobs in the world, and the most prominent companies are looking for data analysts. The salary and perks of a data analyst only show how much people want to do this job, which is likely to keep growing by leaps and bounds.
So, if you have the skills to become a data analyst, you would be foolish not to take advantage of this situation. In this article about the “data analyst job description,” we’ll look at all the different parts of this job and then talk in depth about what a data analyst does.
What Is Data Analysis?
Data analysis is the process of cleaning, analyzing, interpreting, and showing data in different ways using different methods and business intelligence tools. Data analysis tools help you find key insights that can help you make better, more successful decisions. It is about turning raw data into statistics, information, and explanations that make sense.
What do they do?
A data analyst looks at groups of customer information to find ways to solve problems. A data analyst also tells management and other important people about this information. These people work in various fields, including business, finance, criminal justice, science, medicine, and the government.

Data Analyst Skills Required
Now that you know what a data analyst does let’s look at the skills you’ll need to get the job. A good data analyst must have technical skills and the ability to lead. If you want to become a data analyst, a background in math, statistics, computer science, information management, or economics can give you a good start.
Key Skills for a Data Analyst
- Strong math skills to help collect, measure, organize, and analyze data
- Knowing how to code in SQL, Oracle, R, MATLAB, and Python is essential.

What tools do people who look at data use?
The SQL is one of the essential tools for analysts because many large companies use it to analyze data. SQL is also used by software engineers when they make new software. SQL is a computer language used to manage data from relational databases. It is a tool that is easy to learn and can be used to analyze data that is complicated and hard to understand. It is a popular choice among data analysts because the code is easy to read and understand and can be used to change and edit data. Also, it lets you combine data in a way similar to Excel, but for massive datasets and many tables simultaneously.
As a data analyst, you should know how to use Excel, the essential tool. It’s easy to learn, and data analysts should be able to use all of Excel’s features, from formulas to pivot tables. Any spreadsheet program will work, but the most popular one is Microsoft Excel.
SPSS and VBA
In addition to the tools listed above, analysts often need a statistical analysis program like SPSS. SPSS is excellent for analysts who just got their licenses (more on SPSS below). VBA, which stands for Visual Basic for Applications, may be needed by data analysts with more experience. It is a programming language that was made just for Excel. Often used for financial analysis. It also works with Word and PowerPoint. Matlab is another excellent tool that can be used to make algorithms, build models, and look at data.
Project Jupyter is a one-of-a-kind service for making open-source software, open standards, and interactive computing services. It can be used with a lot of different programming languages. Jupyter Notebook is an open-source online tool that lets you make and share documents with live code, equations, graphics, and written prose. The notebook can be used for many things, like cleaning and transforming data, machine learning, and more.
Another important and widely used tool in data analytics is the open-source programming language R, which works on all platforms (Windows, Mac OS, and Linux). It is used a lot for statistical modeling because it has so many statistical and graphical options. Also used a lot for data wrangling and can be found in many libraries, such as Plotly, and lets data analysts make plots and graphs to show how the data looks.
It is used in banking, sales, and several scientific fields, such as medicine and technology. To use this tool for analyzing data, you need to know a little bit about statistics and programming in general.
Tableau is another program that data scientists often use. It is used frequently because it makes it easy to evaluate data quickly. Visualizations can also be done with dashboards and spreadsheets. Tableau lets you make dashboards that show information that can be used to move a business forward. Tableau products always run in virtualized environments when they are set up with the correct operating system and hardware.
SAS, which stands for “Statistical Analysis System,” is a well-known business suite of business intelligence and data analysis tools. In the 1960s, the SAS Institute made it, and since then, it has changed. Its main uses are profiling clients, creating reports, mining data, and making predictions.
The software is often more reliable, flexible, and easy to use for large enterprises because it is made for the business market. This is because they have different levels of programming skills in-house.
Power BI from Microsoft
Microsoft Power BI is a relatively new tool for analyzing data. It has only been around for a few years. It started as an add-on for Excel. In the early 2010s, it was updated to become a full suite of tools for analyzing corporate data. Power BI makes it easy for users to quickly create interactive visual reports and dashboards.
Its best feature is how well it connects to data. It works well with Excel, as you might expect from a Microsoft product. Still, it works well with text files, SQL servers, and cloud sources like Google and Facebook Analytics.

Now that we know what data analyst does and what skills they need, let’s find out more about what makes a good data analyst. To do well in a career in data analytics, you need more than just technical skills.
A bachelor’s degree in a field that emphasizes statistical and analytical skills is preferred. Students with a background in math, statistics, computer science, or economics often have an advantage in data analysis. But a postgraduate course in data analytics like Data Analytics Bootcamp can help you become a professional who is ready to work.
You would also need soft skills to be a good data analyst, such as:
