We have generated so much data that 90% of the total information worldwide was created only over the last two years. The total volume of data generated, captured, duplicated, and consumed worldwide is predicted to grow very fast, estimated to reach 59 zettabytes in 2020 and 149 zettabytes by 2024 (Holst, 2020).

The entire world creates around 2.5 quintillion bytes of data on a daily basis (Gour, 2020). And with the proliferation of the Internet of Things (IoT), this pace is likely to further accelerate, predicted to create 79.4 zettabytes of data by 2025 (O’Dea, 2020).

Along with the breakneck speed of data explosion is the corresponding expanding demand for data scientists. For public, nonprofit, and for-profit organizations, this means an ever-increasing reliance on this new breed of data experts to help the organizations thrive and remain relevant in this constantly changing data-driven world.

What Is a Data Scientist?

What’s the “sexiest job" of the twenty-first century? In a Harvard Business Review article, authors and IT experts Davenport and Patil (2012) raised that evocative question to provide an illuminating discussion about data scientists. (Of course, their answer to that question is data scientist.) Today, as organizations from all sectors and industries struggle with unparalleled amounts of data, they also compete in a tight race to address their need to hire data scientists.

Definitions

Data science is an emerging field that uses combined algorithms and scientific methods to draw out knowledge and gain insights from structured and unstructured data (Bowne-Anderson, 2018). Data scientists are analytical data experts with specialized technical skills and inquisitiveness to detect and solve problems. They collect, analyze, and interpret massive volumes of data to help businesses make better decisions and create value to profit from them.

In a nutshell, data scientists are a new generation of data experts with specialized skills to solve data-related problems and unique acumen to decipher complex technical issues. A data scientist is part business analyst, statistician, programmer, coder, database administrator, artificial intelligence (AI)/machine learning (ML) specialist, trend spotter, data miner, project manager, etc.

In addition, the growing importance of data scientists signals the collective shift towards the increasing reliance of businesses on big data, AI, and ML (Agarwal & Dhar, 2014). The enormous volume of unstructured information had ceased to be neglected and unutilized. With data scientists, this massive amount of data produced on a daily basis has become a virtual organizational resource for market information that can be easily converted into profits and new growth opportunities.

At present, breakthroughs in automation, AI, big data, and ML have heightened the benchmarks of data science tools for business. From working mostly by themselves, data science teams have been formed, composed of business analysts, engineers, citizen data scientists, and expert data scientists. Their presence and impact extend across business units.

Origins

Many data scientists tend to start their careers as data analysts or statisticians. But as the creation of massive data started to further accelerate, those initial job functions changed as well. Data has stopped being a mere second thought for IT to manage. It has become essential information that needs scrutiny, creative interest, and a flair for converting high-tech concepts into new strategies to create value for the organization.

It was in 2008 when the term data scientist became widely-used. After less than a decade, pursuing a data analytics degree is considered as one of the top careers in the United States by 2016 (Mills et al., 2016). This relatively new job position has become so essential to organizations across industries that it is one of the highest-paid jobs in the tech industry. Today, entry-level data scientists earn an average salary of $85,143, while their senior counterparts earn $158,462 on average (Burtch Works, 2019).

The data scientist function also originated from the academe. Around a decade ago, colleges and universities started to recognize the urgency of incorporating data science fundamentals into their curricula. Initially, professors gradually integrated data science subjects in their syllabi until their institutions are able to offer actual data science degrees to tertiary students.

Moreover, secondary and primary schools around the world have started to integrate data science into their K-12 subjects, such as the Mobilize Introduction to Data Science curriculum. Mobilize breaks barriers by teaching students to apply concepts and practices from computer science and statistics in order to learn science and mathematics (Gould et al., 2016).

How to Become a Data Scientist?

Data scientists are well-trained and highly educated although there are some rare instances where robust educational training is tapped to develop the extent of requisite knowledge and skills to be a data scientist. According to Simplilearn (2018), 46% of all data scientists have a doctorate degree, while 88% are master’s degree holders.

As the shortage of data experts continues, pursuing a career in data science remains a smart choice. Aside from having numerous employment options, it also offers an opportunity to start your own company by learning the steps to starting a LLC. In addition, it allows you to grow and develop in an IT field teeming with creativity and innovation. Here are the two most common paths to becoming a data scientist:

Students

To become a data scientist, you need to earn a bachelor’s degree in data science. In case local tertiary schools do not offer this program, the option is to complete courses in statistics, physical sciences, social sciences, and computer science. Earning a degree in any of these courses will provide you with the foundational knowledge and skills to handle and analyze any type and volume of data.

A crucial first step is to select the right school that offers a good data science degree or an available equivalent. Princeton, Cambridge, and Yale are considered among the top schools in the U.S. to earn an undergraduate degree in data science (Bayern, 2019).

According to the Data Science Degree Programs Guide, the top schools that offer the best data science master’s programs for 2019 include Purdue University, University of Rochester, and New York University (DSD, 2019).

Professionals

Aside from formal training in data science, data scientists usually undergo prior training and experience as statisticians or data analysts. However, many also have nontechnical backgrounds, such as management, economics, or marketing.

One might ask, how can people from different backgrounds eventually share a similar career? For an answer, you need to examine what aspects they share in common. All of them have an insatiable desire to know how things work, the proficiency to communicate well, and a talent for solving complex problems.

Foremost of these shared characteristics among data scientists is their profound curiosity. A deep craving to probe the underlying cause of a problem, examine the questions at their core, and condense them into highly understandable inferences that can be analyzed (Davenport & Patil, 2012) is also a prominent attribute of these individuals. This usually involves corollary thinking that defines the most innovative scientists in any discipline.

A Suggested Path to Becoming a Data Scientist

Must-Have Skills for Data Scientists

As the data science field is still evolving, Garten (2018) suggests the value of distinguishing between the deliverables data scientists create as an expedient approach to categorize them. The first type of data scientists can be called modeling scientists. They generate output for machine consumption, e.g., algorithms, training data, and models. Decision scientists comprise the second type. They create output for human consumption, e.g., strategy and product recommendations.

According to LinkedIn, these are the most essential skills set that data scientists should have today:

• Data intuition  Organizations need data-driven problem-solvers to help them address today’s complex market problems
• Text analytics the process of studying unstructured data to extract important business insights.
• Statistics  A reliable knowledge of statistics is crucial to a data scientist’s day-to-day job. 
• Data preparation involves converting raw data into a different format to allow for easier consumption.
• Data wrangling  Always expect to work with unruly data that you must process and make orderly and usable. 
• Programming skills Whatever organization you will be working for, you are likely going to be expected to know how to utilize various data-focused technologies.
• Pattern recognition Technical knowledge that identifies patterns in data.
• Machine learning A type of artificial intelligence that mainly employs automation and mathematical algorithms.
• Deep learning A set of algorithms in machine learning research that utilizes data to frame complex abstractions for automated classification and prediction.
• Software engineering  It is indispensable to have a strong software engineering background

Typical Job Responsibilities of Data Scientists

As a relatively new and evolving organizational function, the data scientist’s role is still in a state of flux. But these are some duties and responsibilities that data scientists are likely to perform:

• Gather large volumes of disorderly data and convert it into a useful format.
• Employ data-driven methods to solve business-related problems.
• Operate using a toolbox of programming languages, such as Python, R, Java, and MATLAB.
• Perform statistical data treatments, such as factor analysis and tests.
• Apply sophisticated technologies such as text analytics, deep learning, and machine learning.
• Collaborate and communicate with both business and IT units.
• Search for patterns and order in data (e.g., useful trends), to frame meaningful insights to support decision-making.

There are several data science processes or lifecycle frameworks that aim to comprehensively establish what the job of a data scientist is. Mason and Wiggins (2010) proposed a simple, yet robust model called the OSEMN framework, which effectively captures a data scientist’s job, from gathering the data, up to data analysis, and results presentation. Moreover, this framework can be used as a guide for solving data problems.

When Is an Organization Ready for a Data Scientist?

Being the current highest-paying job (Comparably, 2019) in the U.S., it is relatively quite easy for data scientists to accept offers or get hired. However, before applying for or accepting a data scientist job in a company, there are a few considerations about the organization you should examine:

• How it values data. Key to making the decision of whether to hire a data scientist or not is a firm’s organizational culture. It should have an environment that supports data analytics and unwavering executive backing. In the absence of these factors, any investment in data science will be hampered and remain ineffective.
• Big data handling capability and protocols. A company must have two major requisites to justify the hiring of a data scientist. First, it should have the need to manage massive volumes of data. Second, they should be dealing with complicated data-related issues on a daily basis. 
• Readiness for change. Data scientists have gained their industrial importance mostly due to the extensive possibilities for advancement that they bring to any organization. However, these potentials would be worthless unless the company is willing to follow the path to organizational change that data scientists recommend.

Just like any method or tool, data science is not for everyone. An organization should clearly determine that it needs a data scientist to improve its operational performance. Likewise, an organization must have the right mindset and the willingness to embrace change.
