Data analysis is the process of transforming data into insights. It gives organizations the ability to support strategic business decisions.

In a nutshell, this practice involves collecting data from different data sources, cleaning data to remove errors, and then applying different techniques to find patterns and identify anomalies. While the role of data analysts might be often confused with data scientists, those roles are not exactly the same.

By using tools like data visualization and techniques, such as creating charts with Power BI or Microsoft Excel, you can present data in a way that helps stakeholders interpret it and make informed decisions (this is what the industry calls “data-driven decisions”).

In essence, it’s all about using technical skills, different languages, and methods such as predictive modeling to analyze the data, predict future trends, and ultimately support the so-called data-driven insights.

What does a Data Analyst do?

A data analyst does many things, because the role itself is very versatile, it involves everything from collecting data to the presentation of findings (i.e. plotting results in charts, or presenting reports with found insights) and everything in between.

To be more specific, a data analyst's work revolves around collecting and gathering data from databases, spreadsheets, and other data sources (usually structured data sources). They perform data analysis by cleaning data and then applying techniques such as regression analysis, and data mining to model data. The final aim is to identify trends and predict outcomes.

With a strong foundation in both computer science and data science, they can use different programming languages and various tools to analyze data and generate reports or visualizations that support strategic decisions.

By the nature of their work, no matter if they’re finding anomalies, performing predictive analytics, or simply solving problems with data-driven insights, data analysts function at the intersection of tech skills (i.e. coding) and business intelligence (they can’t produce meaning results if they don’t understand the business), transforming an organization’s data into data-driven decisions.

What skills are required for Data Analysis?

There are several skills required for data analysis, and they’re all technical skills. Data analysts must start by getting a solid foundation in working with raw data. They then need the ability to ingest and collect data from different sources—be it through databases, spreadsheets like Microsoft Excel or Google Sheets, or specialized data collection tools.

Once you’ve gathered the data comes data cleaning. This means removing inconsistencies, errors, and outliers so that your data sets are accurate and reliable. Techniques like statistical analysis and data mining help you identify anomalies and ensure that you’re working with data that truly represents your problem universe.

With the clean data, the next logical step is to analyze it. This involves using several techniques, such as regression analysis, and statistical modeling to recognize patterns and trends. In the end, the end goal is to learn from the data and share those insights with the business.

When it comes to skills, understanding and having proficiency in languages such as Python or R, along with expertise in various tools like Power BI, are incredibly valuable here. They enable you to perform predictive modeling and even apply machine learning techniques when needed.

Data analysis is a good career choice, in fact, it's a great career choice if you think about how technology is at the core of every company, and by definition, company operations produce data that can later be used to gather insights. Using these insights to drive decisions, and innovation and decide the future of the company, helps ensure these decisions are based on reality.

With organizations increasingly relying on data to support decision-making, the demand for professionals who can analyze data, interpret data, and identify future trends is exceptionally high.

This field not only offers the opportunity to work as a data analyst and develop your findings using different analysis and mining techniques, but also allows you to be a key player in making strategic business decisions.

The field of data analytics is continuously growing and advancing with new techniques, AI-driven analysis or even new visualization tools, ensuring that a career as a data analyst is both challenging and rewarding for those who want to stay competitive and solve problems with actionable knowledge.

Data analysts are generally well paid, reflecting both the complexity of their role and the high demand for their data analyst skills. While salaries depend on experience, location, and industry, data analysts are usually very well paid.

For example, according to Glassdoor, data analysts start with an average salary of 111,000 USD in the United States, and can go up to 140,000 USD (on average) after 10 to 15 years of experience.

The ability to collect and analyze data, through the use of sophisticated tools that generate insights makes data analysts invaluable to organizations of all sizes.

The current labor statistics and market trends indicate that data analysts continue to be in high demand.

To be a data analyst, most employers look for a solid educational foundation, usually a bachelor's degree in computer science, business administration, or data science.

However, the needs of the organization tend to also determine the type of qualifications needed to get the job. Besides formal education, practical experience with programming languages, data tools, and data cleaning is crucial.

You need to be comfortable using tools like (or similar to) Microsoft Excel, Power BI, or Google Sheets to collect data and perform analysis. On top of that, proficiency in statistics, predictive modeling, and even a touch of machine learning are all great skills to have, along with the ability to communicate what you find clearly, this last one being key because as a data analyst you'll be doing it quite a lot.

Many successful data analysts develop these skills through a mix of formal education and self-learning, allowing them to analyze and model data, gathering insights from it.

Yes, you can definitely teach yourself data analysis. Many devs looking to become a data analyst have built their careers by self-studying the principles of statistical analysis, and predictive analytics. Just like with any other technical profession, if you are able to pick up the knowledge on your own, you're more than capable of applying it on your day-to-day.

And to get there, you can use one (or several) of the many online courses, tutorials and roadmaps (like this one) that cover everything from data collection and data cleaning to using advanced languages and data tools. Pick the ones that resonate with you the most, and go for it.

The more you learn about the data analyst role and how to create effective data visualizations, the more you develop the technical skills necessary to support informed decisions and drive business intelligence. The first step is to start with the basics, such as understanding how to work with raw data and performing statistical analysis, and then gradually move on to more advanced topics like machine learning.

With dedication and continuous practice, you can acquire the necessary data analyst skills and become a successful data analyst without formal classroom training.
