Growing Your Data Science Career: From Analyst to Data Scientist 

There are two primary ways you can use data science skills to grow data-centric careers: become a data science professionalpursuing jobs like data analyst, database developer, or data scientistor transition into an analytics-enabled role like a functional business analyst or a data-driven manager. Both career paths require foundational skills and knowledge in data analytics, programming, data management, data mining, and data visualization.

edX_Data-Science-Career-Guide_Graph-3_1600x1800

Despite the two tracks, the evolving nature of the relatively new field means career paths are flexible. Data science professionals like data analysts can lean into a data science or data system developer role depending on where they deepen their expertise. By expanding knowledge in artificial intelligence, statistics, data management, and big data analytics, a data analyst can transition into a data scientist role.By building on existing technical skills in Python, relational databases, and machine learning, a data analyst can become a data system developer. Much of these skills can be learned either from work experience or independently through data analytics boot camps or from online data science courses. In this guide, we focus primarily on the data science jobs track.

Data Scientists vs. Data Analysts: What’s the Difference?

The skills and job responsibilities of entry-level data science roles and data analysts often overlap. Both roles require statistical knowledge and the ability to program. However, there is a clear difference in the focus.

What Does a Data Scientist Do?

Data scientists answer questions about the business from the context of data. They leverage data to create new product features and tend to do more modeling and open-ended research. They’ll spend a lot of time cleaning data to make sure that it is usable for their models and their machine learning algorithms. When you watch Netflix and see a personalized list of recommended shows, that’s machine learning algorithms and data science at work.

Additionally, a subset of data science work is predictive analytics. "Predictive data analysis involves more complexity, because, as the name suggests, it predicts what is likely to happen in the future based on data from the past, or based on doing a data crossover between multiple datasets and sources," said Rafael Lopes, a Partner Solutions Architect at Amazon Web Services and instructor for Getting Started with Data Analytics on AWS. "In a nutshell, it tries to predict the future based on actions from the past. The use of neural networks, regression, and decision trees are very common in diagnostic analysis."

Core Data Science Skills

  • Big data: All data is large or complex data sets that can’t be managed with traditional data processing software. That’s why data scientists must know Apache Hadoop or Apache Spark, which is an open-sourced distributed processing system.
  • Data modeling: data modeling is the process of formatting specific data into a database.
  • Data visualization: data visualization is the graphic representation of data used to show trends and insights.
  • Machine learning: machine learning is a series of techniques used to predict and forecast data.
  • Programming: knowing programming languages such as Python and R are critical if you want to automate data manipulation.
  • Statistics: although you don’t have to be a statistician, you must know some form of applied statistics to interpret data.
  • Teamwork: data scientists don’t work in silosーthey’re often part of larger data science teams comprised of data engineers, software developers, and others.

What Does a Data Analyst Do?

Data analysts are responsible for answering questions about data. Unlike data scientists, data analysts are not concerned with using data to find trends or figuring out the business’s future. Their job is to analyze historical data, create and run A/B tests in product, and even design systems. Data analysts need to be proficient at data storing, warehousing, and utilizing tools such as Tableau.

Core Data Analyst Skills

  • A/B testing: A/B testing is a statistical approach used to compare two versions of a variable in a controlled environment. A/B testing is employed to determine which variable version performs better.
  • Domain knowledge: you can think of domain knowledge as specialization. For example, if you have significant experience working specifically in the retail sector, you have domain knowledge in retail.
  • ExcelMicrosoft Excel is often used to manage small data sets.
  • Data Visualization: like data scientists, data analysts must know how to use data visualization tools such as Tableau to tell stories to stakeholders with data.
  • Programming: data analysts should have competent programming skills in languages like R and Python.
  • SQL: SQL is a database language used for data management and building database structures. SQL is often used instead of Excel because it’s more apt at handling large datasets.
  • Reporting: as a data analyst, you need to report your data insights, which means you should also have excellent communication and presentation skills.

Which Data Science Career is Right For You?

Deciding whether a career in data science is right for you is more than asking if you like working with data or not. It’s about asking yourself if you like working on complex, ambiguous problems and figuring out if you have the aptitude and patience to build your skillset. To determine if a data science career is right for you, ask yourself: 

  • Are you committed to learning technical subjects?
  • Are you willing to learn applied statistics and other types of advanced mathematics like linear algebra?
  • Do you enjoy storytelling with data? 
  • Are you a self-starter and willing to generate new projects to work on independently? 
  • Do you enjoy computer science and programming? 

If you said yes to at least three or more of the above questions, then you may have what it takes to succeed as a data science professional—but which type of role makes sense?

Are You a Data Analyst?

Data analysts are generalists, which means they get to work in different teams and roles. They enjoy working on clearly defined, structured problems. They use data to extract and produce reports that are valuable to a business. Successful data analysts generally enjoy some level of complexity, but not as much as data scientists. Here’s how you can tell if you are fit to become a data analyst:

  • You are a generalist.
  • You enjoy working cross functionally.
  • You enjoy solving concrete problems.

Are You a Data Scientist?

Data scientists love complexity. They enjoy answering questions that are broad and amorphous. They thrive on project-based assignments, and get excited about delivering insights. Data scientists are less likely to work on a wide variety of assignments in comparison to data analysts. Therefore, you might be a good fit for a career as a data scientist if: 

  • You enjoy complexity.
  • You enjoy ambiguity.
  • You like delving into a single question.
  • You’re okay with not finding an answer to a problem.

Are You a Data Engineer?

Data engineers are very technical. They essentially organize and give structure to raw data in order for the data scientists and data analysts to execute their work. A good data engineer enjoys building data pipelines and likes software development. They have an advanced understanding of programming languages such as Java, SQL, or SAS. Therefore, you’ll be an ideal candidate for data engineering if: 

  • You enjoy highly technical roles.
  • You like building and managing data infrastructures.
  • You enjoy software development.
