DJ Patil and Jeff Hammerbacher coined the title while working at LinkedIn and Facebook, respectively, to mean someone who “uses data to interact with the world, study it and try to come up with new things.” Data Scientist Although they purposefully kept the term vague to encapsulate the broad nature of the field, a common argument goes: “Data science is a science, so you need to be an experienced PhD to be a practioner.” Others simply denounce “ ” with “no knowledge of the fundamental theory of the field.” As another article , “data scientists must learn Python.” fake data scientists puts it However, we can clearly see in a few ways that a data scientist doesn’t need an advanced degree, coding expertise, or even a lot of experience: The FAANGs, LinkedIn, and most companies don’t ask for advanced degrees. No-Code and low-code data science don’t need technical expertise. Many leading Data Scientists don’t have advanced degrees. Data science bootcamps bring many people into the field without a degree. Many PhDs lack the practical experience to work in the field. . 1. The FAANGs, LinkedIn, and most companies don’t ask for advanced degrees Remember how analysts at Facebook and LinkedIn coined the term “data scientist?” Well, PhDs (or even Master’s) aren’t a requirement at either of those companies, or almost any of the . 100+ companies hiring data scientists right now As a Facebook exec : writes “We’re looking for talent, no matter what their background.” Indeed, Zuckerberg himself is a drop-out. If we look at a at Facebook, we’ll find BS “or equivalent experience” in the job requirements. Data Scientist job opening The same is true for this “ ” role at Google — asking for a “BA/BS degree or equivalent practical experience.” Product Analytics Lead, Data Science The “or equivalent practical experience” is featured after the preferred degree in every opening I looked at, even in a . Data Scientist Lead role Looking at similar roles at LinkedIn, there are asks for a “BS equivalent experience.” or At Amazon, data scientist roles ask for a Bachelor’s degree. Even this role requires just a Bachelor’s. like this one Senior Data Scientist At Apple, “prefers” a Master’s while explicitly asks for a Bachelor’s. this Data Scientist role this role Like Google, Netflix doesn’t require a degree at all. 2. No-Code and low-code data science don’t need technical expertise. In the Internet’s early days, building a website required serious technical prowess. Now, no-code tools like Wordpress and Wix enable anyone to quickly launch a site. This “ ” process has occurred in many fields, including design (Canva), information (Google), computing (Apple), commerce (eBay, Shopify), and now in data science, with no-code tools like . democratization Apteo While the early days of data science required considerable experience across a range of fields, today’s solutions are more “plug-and-play” than ever. Now, anyone can “turn data into insights,” including making visualizations and predictions on data, without any code. 3. Many leading Data Scientists don’t have advanced degrees. By now, you might be saying: “Sure, companies don’t need advanced degrees, but those with advanced degrees make better data scientists.” This is also wrong. Data Scientists like Nate Silver and Paul DePodesta, who helped popularize the field, have , but no advanced degrees. Hammerbacher, who we mentioned earlier as he helped coin the term “data scientist,” only has a bachelor’s in mathematics. bachelor’s degrees in economics Kaggle’s top competitor doesn’t have a Ph.D., and Kaggle’s CEO himself admonishes the lack of practical thinking he sees in some data science PhDs: “Ph.D.s in computer science and statistics spend too much time thinking about what algorithm to apply and not enough thinking about common sense issues like which set of variables (or features) are most likely to be important.” 4. Data science bootcamps bring many people into the field without a degree. There are many bootcamps or “skills training” courses that teach the skills necessary to be a data scientist, regardless of their academic background. In fact, these are extremely valuable for the industry, as they help to fill the . shortage of tens of thousands of analytics professionals For instance, has taught 75,000+ students, with graduates at companies like Facebook, Microsoft, IBM, Spotify, and Amazon. BrainStation teaches the skills you need in 15 weeks, and even guarantees your money back if you don’t get a data science job. So much for “you need an eight-year Ph.D.” FlatIron’s data science program Other data science bootcamps, like , boast that over 2,250 of their graduates have been hired. Galvanize 5. Many PhDs lack the practical experience to work in the field. Although some point to a Ph.D. as a “holy grail” to enter the field, this couldn’t be further from the truth. Even with a Ph.D., you’d still need to acquire practical skills to work in the field. As one Ph.D. graduate : wrote “I had just walked away from 8 years of study and hard work with no plan.” In 6 months, she taught herself the practical skills to become a data scientist, as any Ph.D. would need to do. In other words: “A Ph.D. is not enough,” and many books and courses exist to re-train academicians to acquire more practical skills. Many will admit that “you don’t need a PhD to do data science,” and there are several factors that can hold back PhDs, such as: PhD data scientists “Stereotypes about the poor quality of academic code.” The “academic bubble.” “PhDs tend to be bad at marketing themselves.” “In academia, people stick to their niche and end up speaking only to others in their discipline.” You absolutely do not need a Ph.D. to be a data scientist, and while it can help, it can also hold you back.
