Information is power, and nowhere is this more prescient than in the world of big data. Even seemingly innocuous data can—when collected and analyzed—produce actionable insights for businesses. This is why the fields of data science and data analytics are now experiencing rapid growth, with the number of data science jobs increasing by 650% since 2012, and data analytics jobs looking to increase by another 22% before 2030. 

However, the terms “data scientist” and “data analyst” are so often used interchangeably that it can be difficult to parse their differences. And this can be especially confusing if you’re trying to break into the field of big data. That’s why we’ve created this guide. Below, we’ll detail the skills and background needed for each role, in addition to their respective salaries. 

Is There a Difference Between a Data Analyst and a Data Scientist?

There is no official standard that dictates when a role should be titled “data scientist” or “data analyst,” so you will likely come across various overlaps and contradictions when browsing the job market. However, many consider the role of a data scientist to involve more coding, deeper analysis of data, and investigations into more abstract questions. 

The Discipline

To fully understand the differences between the two fields, let’s have a look at their respective definitions. 

What Is Data Analysis?

What is data analysis

Data analysis refers to the in-depth study of data in order to find patterns that can be translated into useful insights. When structured and queried appropriately, formerly incomprehensible data can become a goldmine of relevant and profitable information that can be used by companies in all kinds of industries.

For example, data analysis can tell a clothes shop what product is most popular at what time and with which demographic—which can then help staff decide what kind of promotions to run. Data analysis can also help social media sites work out what, when, and how to advertise to individual users in order to maximize the number of clicks.

Data science shares an ultimate goal with data analysis: finding valuable insights within mountains of complex or seemingly trivial data. Often, rather than carrying out the analysis itself, data science focuses on designing the models and writing the algorithms that will be used during the data analysis process. 

While data analysis uses past data to provide insights that can inform future decisions, data science aims to use that data to predict the outcome of future decisions. The developing fields of machine learning and pattern recognition are used to make predictions based on extremely large volumes of past data.

The Role

Now that we’ve covered the outlines and objectives of data analysis and data science, let’s look at how the roles of data analysts and scientists contribute to these goals.

What Does a Data Analyst Do?

Data Analyst vs. Data Scientist - What does data analyst do?

Unsurprisingly, a data analyst analyzes data. This involves collecting data from different sources and putting it through the processes of data wrangling and data mining. These processes structure and glean insights from the data that can then be presented to those who might act on them.

A data analyst is often given questions by stakeholders and decision-makers and asked to find a way to answer them. This means collecting and correlating relevant data and piecing it together to create a bigger picture.

A data scientist can have a few varying roles within a company, some of which are very similar to a data analyst—including collecting, cleaning, and analyzing data to gain useful information. However, where a data analyst is likely to have received specific questions to find the answers to, a data scientist might instead analyze the same set of data with the objective of unearthing patterns that could lead to a new line of inquiry. In other words, a data scientist has the job of finding the right questions, as well as the right answers. 

Aside from this, a data scientist will design models and write algorithms and software aiming to streamline the data analysis process for both themselves and their data analyst team members. A recent study found that cleaning and structuring data takes up more of a data scientist’s time than any other task, so constant efforts are being made to automate more and more of this process so that more time can be devoted to analysis.

A data scientist is also more involved in the field of machine learning (deep learning) and aims to push the boundaries and discover new ways for this technology to be put to practical use in a business setting. This can include running models that predict possible outcomes of hypothetical situations posed by the data scientist. 

Education, Skills, and Background

Data Analyst vs. Data Scientist Skills

Skills and requirements as listed on job postings can be a bit idealistic and a little vague. Here is a more concrete list of technical skills data analysts and data scientists need to get their jobs done. 

What Skills Does a Data Analyst Need To Succeed?

The beginning of a project for a data analyst often comes in the form of desired information or answers to questions posed by stakeholders and higher-ups in the company. The end of a project is the presentation of the acquired insights and answers to these questions. In order to get from point A to point B, the following data analyst skills are required and expected from employers:

  • The ability to take questions and requests posed by non-technical employees and determine what kind of information is acquirable and from what kinds of data.
  • Proficiency in programming languages such as Python (and its packages,) SQL, R, and SAS in order to collect, wrangle and analyze the relevant data.
  • Excellent research skills to obtain a deeper knowledge of the questions posed and answers desired so that data sets can be enriched in order to increase the value of the insights they can provide. 
  • Proficiency in data visualization tools which will be used to showcase data-derived insights in a format that’s easy to comprehend by people of both technical and non-technical backgrounds.
  • Excellent communication skills to ensure that all the valuable information obtained is clearly and accurately conveyed to the right people so that action can be taken.

What Skills Does a Data Scientist Need To Succeed?

As well as finding answers, a data scientist often also has the job of posing questions or determining valuable questions to pose. They are often tasked with the “unknowns,” such as using predictive models to project potential outcomes of business decisions or future industry trends. They also design and write algorithms, models, and software that can help to automate the process of cleaning and wrangling data. 

Most employers will expect you to have the following data science skills

  • Experience in data analysis and its processes (data discovery, data wrangling, data mining). Knowing how data works and what kinds of insights might be hiding within it is essential for a data scientist to pursue new lines of inquiry. 
  • Deep knowledge of machine learning, artificial intelligence, natural language processing (NLP,) statistical models, and other related fields in order to tackle the task of projecting the potential outcomes of various situations. 
  • Fluency in the programming language Python and other data analysis tools for designing new models and writing new software that can help organize, structure, and clean data with less manual work. 
  • Excellent soft skills in order to facilitate smooth collaboration between varying teams and departments. This is useful for collecting data from different places, deepening one’s understanding of the topic being analyzed, and communicating results.

Career Path

Nobody becomes a senior data analyst or data scientist overnight—once their education is complete, the average graduate starts off in a junior role and then works their way up.

What Is a Typical Career Path For a Data Analyst?

When it comes to data analysis, building a foundation of knowledge and experience in handling, manipulating, and wrangling data is crucial. Many current senior data analysts have bachelor’s degrees or master’s degrees in related fields. However, as demand increases, more and more people are taking specific data analysis courses at colleges and online. This includes attending online bootcamps as a substitute for a college degree. 

For most data analysts, their first role will be as a junior in a larger data analysis team, where they will learn the basics of the job in a practical setting and build up a lot of experience in data wrangling. After a couple of years, a data analyst’s role will expand to include more responsibility and chances to lead and help shape projects. At the most senior level, data analysts become team leaders and take charge of deciding and allocating projects. 

What Is a Typical Career Path For a Data Scientist?

A data scientist must make a similar journey to a data analyst. However, in order to be able to delve as deep into data as they do, data scientists also have to build up a strong foundation and familiarity with data. Traditionally, data scientists often come from mathematical backgrounds with PHDs in statistics, computer sciences, and economics. Nowadays, there are college programs and online bootcamps dedicated to data science, and this is how the next generation is being taught. 

Before diving into the depths of machine learning and mapping out predictions, a junior data scientist will likely land a role with an emphasis on data wrangling. The process of readying data for analysis is so varied from case to case that it’s a lot easier to learn through hands-on experience. Once familiar with the practicalities of data analysis, a data scientist can branch out into algorithm and software writing, and deepen their knowledge of machine learning and its applications. A more senior data scientist might go down the path of team lead or management roles, allocating projects and working closely with stakeholders and decision-makers. Alternatively, they may spend their seniority tackling the most complex and valuable questions with their expert knowledge in machine learning and pattern recognition.
