The increased demand for data-oriented products and solutions has driven up the demand for data scientists more than ever before. Data science job listings have soared, with employers offering mouth-watering packages. The figure below shows how much top tech companies are paying their data scientists.
In recent years, few careers have received the same level of hype as data scientists’. Glassdoor has named data science as one of the best jobs in America (Glassdoor, 2021). Organizations need data scientists to perform a plethora of jobs, from data mining and analytics to building recommender systems. The high demand for data scientists has increased interest in the field, from prospective college students to those already in the workforce. Given the soaring demand for data scientists, several master’s programs in data science, business intelligence, machine learning, and other related fields are springing up globally. These programs promise to teach the skills needed to glean business insights from raw data and to help create data science talents (Cote, 2021).
Data science is not just a temporary buzzword, it is a career that is going to be in demand for a long time. Universities are understanding the increasing need for data scientists and are developing programs in response. Data science programs blend aspects of statistics and mathematics with computer science. Given that some of these programs are new, there is a wide range in terms of depth, quality, and breadth of the programs offered. Data science degree programs also require an investment of at least 2 years and can cost thousands of dollars (Vickery, 2021).
This article aims to provide you with comprehensive information on a data science career. We aim to help you enter the data science job market, or enhance your position if you are already there. The next section discusses the relevance of a data science degree, including its advantages and disadvantages, and a discussion on alternatives to a data science degree. This mainly covers massive open online courses (MOOCs), including their pros and cons. A recommendation section will follow, pointing out the best data science MOOCs to pursue. The last sections offer career advice for an aspiring data scientist. (Malmgren D, 2020)
A data science degree—is it worth it?
A formal data science degree offers structure, depth, and social interactions with professors and fellow students. If you fancy these things, then you will benefit from enrolling for a master’s degree in data science.
Getting a master’s degree in data science can yield benefits if you are already working in the field (Berkeley Extension, 2021). It can give you a career boost by allowing you to apply for a senior data scientist position. Some job ads may specifically mention a master’s in data science as a prerequisite. If you don’t have a formal degree, you may miss out on these jobs. A master’s in data science can also give you depth; you will learn more about data science and network with other data science fans.
Notwithstanding the merits of a data science degree, there are some disadvantages to pursuing a master's in data science. Data science degree programs are expensive, with some demanding more than the median household income in the United States (Tayo, 2021). These programs cannot provide you with any information for free or even cheaply. Many universities are offering their data science master's degrees on campus and online through platforms such as DataCamp, Coursera, and EdX. Professors from reputable universities are creating courses on these very platforms and so the courses are of quality and depth, just like master's programs.
A master's in data science can be worth it however. The ability to master data science is a plus for advancing professionally, and having a master’s in Data Science can put you at the front of an interview queue. This is important where pedigree matters to employers. Some employers may even want to look at the schools you went to and your previous employers before deciding to interview you. A data science degree can add a level of prestige to your resume, allowing you to get an early boost in your career.
However, it is possible to learn employable data science skills from online courses on DataCamp, Coursera, and EdX, among others. Therefore, it may be unnecessary to spend thousands of dollars. A data science degree will cost you about $52,000 on-campus and $22,000 online (Masters Portal, 2021). Remember this is on tuition alone, without factoring in living costs. In addition, it will take you about 24 months to complete a master's in data science.
What’s the point of spending all that money and time on a master’s in data science? Some critics claim that many of the programs are not only expensive but also over-promise and under-deliver for future employment (Vickery, 2021).
While many colleges and universities offer data science degrees, there is still a shortage of data scientists.
Another concern about the explosion of data science programs is that while some graduates will get jobs they like and pay them very well, others may not be so lucky. Some newer data science master’s degree programs may over promise students and under-deliver on future employment. Thus, having completed an undergraduate curriculum that covered units in mathematics, statistics, and/or computer science can provide a more comprehensive foundation than a data science master’s degree program.
The next section provides information on how to choose a data science degree program.
Choosing a Data Science Degree
Data science is a broad field that encompasses various disciplines, including mathematics, statistics, economics, business management, and computer science. There is no one best path to becoming a data scientist. Everyone’s path depends on their background. It is important to know the job prospects for a particular graduate program before committing the time and money (Mastersindatascience, 2021).
Many people working in data science jobs mainly have backgrounds in statistics, math, and/or computer science. Typical data science roles include responsibilities such as data preparation for analysis (cleansing, aggregating, and manipulating) and performing advanced data analysis to uncover patterns and information that help businesses to make informed decisions (Oracle, 2021).
The role of a data scientist includes crafting data preparation strategies, preparing data for analysis, exploring, analyzing, and visualizing data, building models (using programming languages, such as Python and R), and deploying models into applications.
Data scientists don’t often work solo. Besides a data scientist, the team may include a business analyst (responsible for defining the problem), data engineer (prepares data), a system architect (in charge of processes and infrastructure), and an application developer (responsible for deploying models or outputs into applications and products).
Understanding what data science is and how it works paves the way for those interested in the field to make informed career decisions. Before moving forward in applying to a data science degree program, consider the following factors:
- Know your data science pathway
At the basic level, all data scientists should have foundational skills in data analysis, statistics, MS Excel, and data visualization. There are two main data science career pathways: data-centric careers (such as data scientist, data analyst, machine learning engineer, and data engineer) and business analytics (functional analysis and business intelligence analyst). The infographic below shows some roles and the required skills.
You will need to consider the path you want to take and follow a pathway to be a leader in that field. This decision can be life-changing if you are returning to school looking to make a clear career change.
- Research the school’s reputation
Data science is a hands-on career that requires a lot of depth and breadth. It carries an enormous responsibility. It is important to assess the school’s reputation for a program. For new programs, assess the university’s reputation, notably in computer science, math, and statistics programs.
- Consult about the curriculum's depth and quality
A comprehensive data science curriculum should include statistical, computational, and professional aspects of data science, such as ethical practices. In addition, a curriculum should teach students how to tell data stories to users. This is a key skill that hiring managers are looking for.
- Research on the alumnus network
You will need to assess the kinds of jobs that graduates hold, and (if possible) the approximate number of those that are working. You will also need to know about networking opportunities. This will ultimately help you get a job in the field.
- Ask about opportunities to build
projects for your data science portfolio A data science project portfolio is more valuable than a resume. A portfolio will outline your projects, including codes and documentation. This can help you get a data science job faster than by just presenting your resume. You need to make sure that the data science degree program allows you to build a portfolio of projects as you go. It is a plus to have a capstone project at the end of the program. Hiring managers hunt for data science talent that has a strong background in skills like Python, R, and SQL. A candidate should have excellent communication skills, and be able to present their results and findings to a non-data science audience. Your resume should outline these skills and link to projects you've completed.
- Enquire about the program’s value to employers
If you are looking to pursue a data science career, then you will need to understand what skills hiring managers are looking for. As a prospective data scientist, choose the best education. There are many opportunities for you to develop and hone your skills in data science. This does not mean that you should quickly sign up for the least expensive option. You will likely want to use your time and money wisely. For every input, you will want to make sure that you get something meaningful that can boost your portfolio or resume.
Can you become a Data Scientist without a degree?
You can become a Data Scientist without a formal degree. A master's degree indeed teaches you a lot about data science. You'll become a confident coder and have strong statistical and mathematical knowledge. However, you don't have to get a university degree to gain these skills. There are many free and paid online resources that'll teach you the ins and outs of programming and data science. Having the right skill set is not enough. You will need to prove your competency. While a master’s degree does show that you’ve put in the time and effort to study data science, it is not the only way to equip yourself with data science skills. Instead of studying for a degree, you can build projects using knowledge from online courses and showcase them to prospective employers (Berkeley Extension, 2021). While it is possible to become a data scientist without getting a master’s degree, you will need to carefully choose what you learn.
The rise of massive open online courses (MOOCs)
Technological advancement has completely revolutionized the education sector. Online education has turned what used to be ‘distance learning’ into live and interactive learning. Dave Cormier introduced the term ‘MOOC’ to refer to a massive open online course in 2008 (Cormier, 2008). MOOCs provide a learning platform that is not limited by time and place. A learner from one corner of the world can get real-time access to a course offered in another corner of the world. All you need is an internet connection. According to Class Central (Class Central, 2021), there are over 1,500 data science MOOCs—with each course averaging over 50,000 enrollments. The success of MOOCs is massive; over 75 million learners have enrolled. In early stages of development, MOOCs suffered problems like student motivation, dropout, and grading of MOOCs. There are issues affecting student motivation, such as learning support, content design, visuals, and self-assessment. Thus, very few universities globally have implemented MOOCs in their curriculum (Class Central, 2021).
Online MOOCs providers have come to fill the gap. MOOCs are widely popular, educating millions of people looking to learn tech skills. The information taught in MOOCs is the same as in degree programs. Online learning platforms like DataCamp are also great for new students, especially those making a career change to data science. You can quickly learn the fundamentals of programming in key languages like Python and R. DataCamp conveniently groups skills required for a particular career into ‘career tracks.’ They also offer many assignments and examples for you to practice concepts and hone your skills. If you want to know more about DataCamp, follow this link.
- Advantages of Data Science MOOCs
MOOCs offer free and paid online courses and are available for anyone to enroll. MOOCs provide an affordable and flexible way to learn new skills (Kursun, 2016). MOOCs cover a broad spectrum of online courses in leadership, analytics, data science, machine learning, professional skills, engineering, business & management, humanities, computer science, and much more. These courses are usually offered by top universities across the world, like MIT, Harvard, UC Berkeley, and the University of Michigan. Some courses are also offered by big corporations, such as IBM, Google, and Microsoft. The greatest advantage of MOOCs is the opportunity they offer to learn from leaders and experts, and the privilege of taking courses from the world's top universities without pouring thousands of dollars into a degree. Even if you already have a computer science background, MOOCs will allow you to gain the skills to prove that you can be hired in data science roles (Romero, 2017).
- Disadvantages of data science MOOCs
If you are interested in exploring the field of data science, I would recommend starting with MOOCs. After building a solid background in data science fundamentals, you may then use the methods discussed in the next section to advance your knowledge in the field. There are numerous data science MOOCs available online. Thus, choosing which ones are right for you can be a challenge.
Most data science MOOCs providers offer a wide range of courses, from introductory-level courses to advanced courses. These courses are good for individuals that don’t have a solid background in a complementary discipline (physics, computer science, mathematics, engineering or accounting). There are even data science specializations that are best in terms of quality and rigor for advancing those with deeper knowledge in complementary disciplines. In summary, MOOCs cover a wider variety of students than data science degrees. It is this wide variety that can present a challenge to beginners when deciding on the appropriate courses to pursue (Parker, 2021).
