become a certified data analyst

Are you interested in earning a data analytics certificate or becoming a certified data analyst? Looking for a way to start working fast? Concerned that you might have to enroll in a lengthy degree program at a major university to learn data analytics?

In the past, becoming a data analyst did require obtaining a bachelor’s degree from an accredited college or university. Fortunately, that is no longer the case.

Below, we’ll discuss what a data analyst does daily. We’ll also identify the skills you need to become a certified data analyst and show you how to earn a data analytics certificate in only 6 months!



What does a Data Analyst do?

In the broadest sense, a data analyst is responsible for gathering, organizing, and cleaning data. Once they have completed these steps, they can analyze and interpret the data to gain meaningful insight into a specific problem or question.

During the interpretation process, an analyst is often tasked with converting the data into a visual chart or graph so others can easily review it.

Data analysts work in various legal, human resources, and marketing fields. Analysts use their findings to help organizations make informed decisions about future policies. For instance, they may use analytics to project how a new product will perform when it is released. Stakeholders will consider this analysis when deciding how much to invest in marketing, how much inventory to create, and more.

What are the top skills required to become a Data Analyst?

Data analysts do much more than just crunch numbers. They are also tasked with communicating with consumers, coworkers, and C-suite executives.

Data analysts also use the latest technologies to compile and interpret data. You can learn many skills by taking a data analytics certificate program. Therefore, they need a diverse set of skills, including:

Creative and analytical thinking

Before an analyst can start gathering data, they must first identify and clearly define the problem they are trying to solve. This requires creativity and analytical thinking skills. They often have to think outside the box and take a nuanced approach to the problems that their organizations are facing.

Once they have selected a pain point to address, they will then need to determine which data analysis will be most effective in answering the question.

There are four broad types of data analytics, which are as follows:

  • Descriptive Analysis (what happened)
  • Diagnostic Analysis (why something happened)
  • Predictive Analysis (what will happen next)
  • Prescriptive Analysis (what will happen and how to change it)

Prescriptive analytics is the most innovative method of the four data analysis types outlined above.

Prescriptive analytics tells businesses what will happen in the future and prescribes ways of influencing that outcome. However, it also requires highly advanced AI and machine learning technologies. Many smaller businesses do not have the resources to leverage this type of analysis.

Data visualization

Data visualization is an essential skill for analysts. Data visualization is the process of representing information in the form of graphs or charts.

While it may sound simple, data visualization is an incredibly involved field that requires analysts to possess specific skills such as a Tableau or Asana Project Management Certificate.

Data visualization is important because it allows analysts to convey their findings in a meaningful and digestible way. While data analysts may be able to interpret information in a raw format, their employers expect the results to be presented through an easy-to-understand visual medium.

Machine learning

For businesses, prescriptive and predictive analytics are the two most useful types of data analysis. Both of these fields require data analysts to leverage machine learning tools.

Machine learning is a field of study that focuses on computer algorithms. Specifically, machine learning involves algorithms that can automatically improve themselves through data collection and experience gained over time.

A data analyst uses machine learning algorithms to recognize and model specific patterns. This produces fairly accurate predictions of what will happen in the future. Business leaders use these insights to make data-driven decisions for their organizations.

Statistical knowledge

Statistical knowledge is also a must-have skill for data analysts. This category encompasses proper data collection methods, analysis protocols, and interpretation.

Statistics can help data analysts to draw meaningful conclusions about important trends using a science-based approach.

Data cleaning skills

No matter how skilled a data analyst is, most data pools contain some inaccuracies or missing values. If they use this data “as-is,” then the analysis and the conclusions drawn will almost certainly be skewed. Analysts must “clean” the data before beginning interpretation to avoid these issues.

During data cleaning, the analyst will detect and correct inaccuracies. Depending on the nature of the issue, they may delete, replace, or modify the dirty data. Once this process is complete, they can analyze and interpret the data sets.

Microsoft Excel

The popular spreadsheet software is a great way to gather data for analytics purposes. It is especially useful when working with small or medium-sized data sets. However, it is not advanced enough to handle big data analysis. As a result, large organizations rely on other data tracking methods, such as SQL.


Structured Query Language (SQL) is a programming language designed for data management purposes.

SQL is a must-have skill for data analysts. SQL databases allow analysts to store their information in organized tables. They can readily access and “pull” data from multiple tables to perform their analysis.


Which certificate is best for Data Analytics?

If you are interested in earning a data analytics certificate, you have probably already conducted some research on your own. You likely found a lot of conflicting information about which programs you will need and what certifications are the best for starting your new career!

Many sources will tell you you need a four-year degree in statistics or a related field. Others may suggest obtaining multiple certifications before applying for your first data analyst position. However, that is not the case.

You can obtain the skills of an entry-level data analyst by obtaining a single certification.

The Tableau Data Analytics Certificate

The Tableau Data Analytics Certificate is the best data analyst certification. This certification is a great option whether you are an aspiring analyst or need to learn new skills to expand your horizons.

Tableau is an end-to-end analytics platform. You can prepare, analyze, clean, and share big data sets with it. This platform is extremely popular among major corporations because of its innovative data visualization capabilities.

Tableau can be used to:

  • Import massive data sets
  • Manage metadata
  • Conduct real-time data analysis
  • Create “no-code” data queries
  • Engage in data collaboration
  • Blend data sets
  • Visualize data
  • Perform business intelligence tasks

Tableau is perhaps the most comprehensive and efficient data analytics solution available today. The company continues to expand its services, which means that the Tableau certificate will be valuable to your data analytics career for years to come.


How long does it take to earn a Data Analytics Certificate?

Now that you have a better understanding of the skills you will need to become a data analyst; you may wonder how long the certification process will take.

Contrary to popular belief, earning a data analytics certificate does not take years — or even twelve months!

With the right program, you can obtain your Tableau certification in just 6 months.

While working through your Tableau course, we also recommend studying SQL. This common programming language is an essential skill for data analysts and is easy to learn. Most students with no prior experience can master the core concepts in a few weeks and become proficient with SQL in months.
