What are the qualifications a data scientist needs?
There is some debate regarding the necessity of a degree to become a data scientist. Although many professionals have entered the industry through other routes, a university qualification can benefit you. Graduate schemes and jobs usually look for individuals with qualifications in computer science, data science, engineering, statistics, mathematics, and even physics. However, some schemes are willing to train anyone with a degree to become a data scientist.
A working knowledge of programming languages such as Python, R, SQL, and Julia can be helpful. However, some people may feel they can rely on their own self-directed learning, developing the required skills and experience at their own pace and convincing employers during interviews.
Also, you can get certified as a data scientist with DataCamp and prove your data science knowledge to potential employers.
How to become a data scientist in 2023?
After reading thus far, you must be excited to start your journey to becoming a data scientist. However, the question remains: where to begin? Below, I have listed eight steps you must take to become a data scientist from scratch. As discussed above, the exact data scientist requirements will depend on various factors; nevertheless, these are some of the most commonly cited steps.
1. Learn data visualization, data wrangling, and reporting
Anyone who works to become a data scientist comes across vast and complex datasets. To make sense of this information for yourself and others, you must learn how to deal with it. Having skills in data wrangling will allow you to clean, organize, and transform raw data into a format you can analyze and draw conclusions from.
Although there are many tools for data wrangling, people tend to opt for libraries like pandas in Python. To present your data effectively, you must master reporting and data visualization.
2. Try to hone your machine learning, math, and statistical skills
Although you exactly require a degree in these fields, you do need to have a basic knowledge of these areas. I recommend you work on essential areas such as calculus, linear algebra, and statistics.
However, we also need to assess your intent behind learning these things. For example, understanding calculus can help you create optimization algorithms for machine learning. Similarly, knowing about gradient descent can enable you to measure the change in a function’s output on tweaking the inputs. That, in turn, can help you refine machine learning models.
3. Learn how to code
Two of the best languages that data scientists should learn are Python and R by virtue of their versatility and ubiquity. Since working with data invariably means working with databases, SQL is another vital programming language for you. Fortunately, it is a relatively straightforward language after learning Python and R.
Julia is a decent choice for people who have learned Python, R and SQL. It is a language specifically optimized for data science, making it fast and intuitive. You might require additional languages if you start working with large data sets; until then, these four will suffice.
4. Work hard to understand databases
Relational databases help data scientists store structured data quickly and efficiently. When collecting and organizing data, you will often discover that SQL is your tool of choice. It enables you to handle structured data, query databases, wrangle, prepare, and experiment with data. Moreover, data scientists often deploy it alongside Python with libraries such as MySQL, PostgreSQL, and SQLite, helping you connect different data sources.
5. Learn to work with big data
I have already mentioned that, as a data scientist, you will frequently have to work with huge sets of data. In the modern era, where data is simply overflowing everywhere, these data sets are becoming increasingly larger. That makes them more challenging to collect, process, and maintain.
Nevertheless, a talented data scientist can extract new and profound insights from these massive data sets. Thus, learning to use cloud platforms such as AWS, Google Cloud, and Microsoft Azure gives you much to gain. Likewise, tools such as Apache Spark can help you out with big data processing, analysis, and machine learning.
6. Try to get more experience, practice, and meet fellow data scientists
Like every other career, you will require as much experience and practice as possible to become a good data scientist. Fortunately, there are several ways for you to become a part of communities, take up projects, and build on your data science skills.
For example, DataCamp Workspace offers a collaborative cloud-based notebook that lets you analyze data, collaborate with others, and share insights. It is designed to take people from learning data science to doing it. It also features built-in datasets enabling you to analyze data within minutes.
