Differences Between Data Scientist and Data Analyst: Complete Explanation

data scientist vs data analyst

The ever-changing world of information technology (IT) has brought us new innovations and ways of doing things and a host of new terms, phrases, and acronyms for us to learn. However, the relative newness of these terms often leads to confusion, as many need more time to bake into our modern lexicon. As a result, terms sometimes overlap, or different sources offer varying definitions.

And that’s an issue with data scientist vs. data analyst. These terms are often used interchangeably despite being two distinctly different jobs with very different roles. This article compares data science and data analytics, provides insights into both disciplines and covers what kind of work data scientists and data analysts do.

Additionally, we will explore the data science skills needed for each career, some salary figures, and how to get started in both occupations.

Let’s begin our journey with some definitions, then move on to the data science vs. data analytics comparisons.

What is Data Analytics?

Before we determine the difference between data science and data analytics, we should establish some definitions. First, data analytics is the discipline of analyzing raw data to draw out actionable, meaningful insights. It helps organizations and people make sense of data by spotting trends and drawing conclusions.

What Does a Data Analyst Do?

Data analysts review data, spot important, meaningful, and valuable insights into the company’s customers, and decide how to use the data to solve problems. Data analysts then relay this information to the appropriate parties, which are typically management and stakeholders.

What is Data Science?

On the other hand, however, data science is a field that combines programming skills, techniques, domain expertise, and knowledge of statistics and mathematics to draw out meaningful insights from data. Data science focuses more on the practice of designing models and writing algorithms used during the data analysis process.

What Does a Data Scientist Do?

Data scientists concentrate on developing and implementing the necessary tools to help data analysts analyze their data and extract vital information from it. They spend their time developing models and preparing algorithms. In addition, if the organization needs to deploy a model, the data scientist takes care of the implementation.

Let’s explore the difference between data science and data analytics.

How About a Clear Comparison of the Two Disciplines?

Sure! To put it in plain language, the difference between data science and data analytics is that data science focuses on the big picture. In contrast, data analytics deals with a more minor, focused purpose. Data science asks the big questions, while data analytics focuses on specific areas.

Let’s use a medical-based analogy to illustrate the data science and data analytics difference. A data scientist is comparable to a general practitioner doctor who studies the patient’s overall health and diagnoses a problem. The data analyst is like a specialist who focuses on that problem (neurological, cardiac, endocrinal) and how to treat it.

Now it’s time to get into the practical aspects of the data scientist vs. data analyst topic.

What Kinds of Education, Skills, and Backgrounds Do Data Analysts and Data Scientists Require?

As we explore the data scientist vs. data analyst question, we must address the fundamental question of what it takes to become data analysts and data scientists. Since the two fields are different, the needed skills and education are different, too, right?

Right. Let’s put together a chart to clearly show the differences between what makes a data analyst vs. a data scientist. You will notice that there is significant overlap, unsurprising considering the similarities of both disciplines.
