What Does a Data Scientist Do?

Utilizing a diverse skill set, data scientists bridge the gap between the massive amounts of raw data generated by organizations every day and the actionable insights derived from that data. Their day-to-day responsibilities may include all or some of the following: 

Data Analyst vs. Data Scientist

While their roles can seem similar, data scientists and data analysts each have distinct responsibilities and functions within their organizations. 

Data analysts focus on interpreting existing data to provide descriptive insights, reporting on past trends, and making data accessible for decision-makers. They often use tools like Excel and SQL to generate reports. Their work often supports that of a data scientist. 

In comparison, data scientists have a broader skill set, combining data analysis with advanced statistics and machine learning. They dig deeper into data, developing predictive models, finding patterns, and creating algorithms to drive future strategies. Data scientists handle complex, unstructured data using programming languages such as Python and R

Data scientists are typically considered more senior than analysts, though they often begin their careers as statisticians or analysts. Think of it this way: Data analysts describe the past, while data scientists predict and shape the future using data.

It’s important to remember that job descriptions often encompass everything and anything someone might be expected to do in a specific role — meaning that, if you don’t think you have all the appropriate experience for an open data scientist role, don’t be discouraged from applying. Hiring managers typically include every eventuality in their job listings, but possessing the majority of the preferred experience can be sufficient to land an interview.

Data Scientist Skills & Qualities

The function of a data scientist combines the work of several other technical and non-technical roles, including mathematician, computer programmer, analyst, and business strategist. Their broad skill set includes both hard, technical skills and more interpersonal skills that help them communicate their data-driven conclusions to business leaders.  

Preferred technical skills include:

How to Become a Data Scientist

There is no one way to become a data scientist; since the role calls for such a broad skill set, data scientists can come from any industry or professional background. That said, there are specific skills and experiences future data scientists should have on their resumes before applying for jobs.   

  1. Earn a relevant degree.  

While not always required, many employers do like to see some relevant academic experience or credentials. Most data scientists hold at least a bachelor’s degree in a related field such as computer science, mathematics, statistics, engineering, or a domain-specific discipline like economics or biology. You can, however, become a data scientist without a degree, provided you gain the necessary skills some other way.

If you would like to further enhance your academic background and qualifications, consider pursuing a master’s degree in data science, analytics, or a related field. By doing so you can deepen your understanding of the many facets of studying data by tackling real-world problems. Many data scientists even have business degrees, since business acumen and strategy can be a large part of the role. 

  1. Sharpen your data science skills.

Whether or not you choose to earn an advanced degree, you should pursue opportunities to build your technical and non-technical skill set. You’ll need to be familiar with common programming languages, statistics, machine learning, data management and visualization, and knowledge of how data functions in a particular industry. If your degree didn’t cover these topics, or if you choose not to earn a degree, many of these skills are available through online certificate courses or boot camps. Speaking of which…

  1. Earn a professional certificate.

Employers like to see that data scientist candidates are committed to pursuing continuing education and professional development. A data science certificate provides you with a credential that conveys your value to future employers and positions you as a candidate for career advancement. 

  1. Gain practical experience.

While learning theory and completing simulations is helpful for getting comfortable with data science, there is no substitute for real-world application. Internships and entry-level analyst positions are great for those just starting out to gain on-the-job experience; many data scientists start their careers as analysts. You can also participate in competitions and connect with others who are honing their skills. If you prefer to work on a personal data science project, you can still add it to your portfolio to showcase your practical skills. 

  1. Build your network.

A professional network is a highly valuable asset when it comes to your job search. Attend data science conferences, workshops, and meetups to connect with professionals in the field (be sure to add them on LinkedIn or another professional platform). Join online communities and forums to learn from others and stay updated with industry trends

  1. Apply for data science jobs.

Once you feel you’ve acquired the necessary education and experience, start applying for relevant positions. Data scientist is almost never an entry-level role, so look for positions with titles such as data analyst, business intelligence analyst, statistician, or data engineer.

As with any position, make sure to tailor your resume and cover letter to highlight your skills, projects, and relevant experience that would be of interest to the employer. Prepare for interviews by reviewing common data science interview questions and practicing problem-solving. Be persistent and apply to a range of positions to increase your chances of securing a job.

How to Advance in Data Science

As you start to build your data science career, keep an eye on industries that have a growing need for skilled analysts and scientists.

You may also want to find a mentor, someone in a more advanced role who has likely been working in the field longer. They may be able to give you advice from their own lived experience and even recommend exploring certain lucrative or rewarding industries.  

Along with finding your own mentor, consider becoming a mentor to someone else, especially as you advance in your organization or career. Teaching is one of the best ways to learn, so passing your recommendations and perspective on to someone who is just starting out can help you build your own confidence or realize your own specialized interests within the data science field. 
Above all, there is no such thing as being too knowledgeable in the field of data science. New data analysis technologies and collection methods are introduced regularly, and the volume of data we generate is only going to grow exponentially. Pursuing an advanced certificate in data science and engineering — such as the online Practical Data Engineering Certificate from the University of San Diego — is an excellent way to demonstrate your commitment to staying agile and up-to-date on the latest tools and best practices.
