How to become a data scientist?
Data science is a discipline focused on extracting valuable insights from copious amounts of data. As such, professionals skilled in interpreting and leveraging data for their organizations’ advantage are in high demand. As a data scientist, you will be instrumental in crafting data-driven business strategies and analytics. Here’s a newly paraphrased guide to help you get started:
Phase 1: Bachelor’s degree
An excellent entry point into the world of data science is obtaining a bachelor’s degree in a related discipline such as data science itself, statistics, or computer science. This degree is often a primary requirement by organizations when considering candidates for data scientist roles.
Phase 2: Mastering appropriate programming languages
While an undergraduate degree provides theoretical knowledge, practical command of specific programming languages like Python, R, SQL, and SAS is crucial. These languages are particularly pivotal when dealing with voluminous datasets.
Phase 3: Acquiring ancillary skills
Apart from programming languages, data scientists should also familiarize themselves with tools and techniques for data visualization, machine learning, and handling big data. When faced with large datasets, understanding how to manage, cleanse, organize, and analyze them is critical.
Phase 4: Securing recognized certifications
Obtaining certifications related to specific tools and skills is a solid way to demonstrate your proficiency and expertise. These certifications often carry weight in the eyes of potential employers.
Phase 5: Gaining experience through internships
Internships provide a valuable platform to kickstart your career in data science. They offer hands-on experience and exposure to real-world applications of data science. Look for internships in roles like data analyst, business intelligence analyst, statistician, or data engineer.
Phase 6: Embarking on a data science career
After your internship, you may have the opportunity to continue with the same company or start seeking entry-level positions elsewhere. Job titles to look out for include data scientist, data analyst, and data engineer. As you gain more experience and broaden your skill set, you can progress through the ranks and take on more complex challenges.

How long does it take to become a data scientist?
“How to become a data scientist?” is a question many aspiring professionals ask, and an equally important question is “How long does it take to become a data scientist?” The answer can vary depending on several factors, including your educational path, the depth of knowledge you need to acquire in relevant skills, and the level of practical experience you need to gain.
Typically, earning a bachelor’s degree takes around four years. Following that, many data scientists choose to deepen their expertise with a master’s degree, which can take an additional two years. Beyond formal education, acquiring proficiency in essential data science skills like programming, data management, and machine learning can vary greatly in time, ranging from a few months to a couple of years. Gaining practical experience through internships and entry-level jobs is also a significant part of the journey, which can span a few months to several years.
Therefore, on average, it could take anywhere from six to ten years to become a fully-fledged data scientist, but it’s important to note that learning in this field is a continuous process and varies greatly from individual to individual.
How to become a data scientist without a degree?
Now that we’ve discussed the traditional route of “how to become a data scientist?” let’s consider an alternate path. While having a degree in a relevant field is beneficial and often preferred by employers, it is possible to become a data scientist without one. Here are some steps you can take to pave your way into a data science career without a degree:
Self-learning
Start by learning the basics of data science online. There are numerous online platforms offering free or low-cost courses in mathematics, statistics, and relevant programming languages such as Python, R, and SQL. Websites like Coursera, edX, and Khan Academy offer a range of courses from beginner to advanced levels.
Specialize in a specific skill
While a data scientist must wear many hats, it can be advantageous to become an expert in a particular area, such as machine learning, data visualization, or big data. Specializing can make you stand out from other candidates.
Learn relevant tools
Familiarize yourself with data science tools and platforms, such as Tableau for data visualization, or Hadoop for big data processing. Having hands-on experience with these tools can be a strong point in your favor.
Build a portfolio
Showcase your knowledge and skills through practical projects. You could participate in data science competitions on platforms like Kaggle, or work on personal projects that you’re passionate about. A strong portfolio can often make up for a lack of formal education.
Networking
Join online communities and attend meetups or conferences. Networking can help you learn from others, stay updated with the latest trends, and even find job opportunities.
Gain experience
While it might be hard to land a data scientist role without a degree initially, you can start in a related role like data analyst or business intelligence analyst. From there, you can learn on the job, gain experience, and gradually transition into a data scientist role.
Remember, the field of data science values skills and practical experience highly. While it’s a challenging journey, especially without a degree, it’s certainly possible with dedication, continual learning, and hands-on experience.
