The Essential Skills for Aspiring Data Scientists
If working in the field of data science is something that interests you, then you may be wondering what kinds of skills you will need to develop to do this kind of work. While this is by no means a comprehensive list of every skill you need as a data scientist, it does cover some of the most important technical skills.
Fundamental Programming Languages to Learn
Many data scientist roles require at least some level of programming knowledge, so aspiring data scientists should focus on learning the fundamental programming languages used by professionals in the field. Some examples of essential languages used in data science include:
- Python
- SQL
- SAS
Data scientists often use these languages to manage, manipulate, and analyze large amounts of data. In some cases, these languages could also be used to automate certain tasks and even build machine learning models, and these are critical skills to have if you want to enter the field.
Mastering Data Manipulation and Analysis
Data scientists also tend to do a lot of manipulation of data as part of their analysis. Specifically, data manipulation involves organizing or even transforming raw data to make it easier to work with. Data scientists may manipulate data by filtering it, cleaning it, or even merging it with other data.
From there, data scientists may have an easier time analyzing data and extracting valuable insights from it. Often, this is done using a combination of statistical methods and modeling.
Importance of Visualization Tools and Techniques
Even once data scientists can extract meaningful information and insights from data, their work may not be complete. In situations where they need to make recommendations or communicate findings to decision-makers or other stakeholders, data scientists may need to use data visualization tools like Tableau, Zoho, and Google Charts.
These tools could be a great way for data scientists to present data in an accessible way that is easier for people outside the field of data science to understand. Specifically, they may rely on charts, graphs, infographics, and other data visualization techniques to get their points across clearly.
Educational Pathways to a Data Science Career
As the BLS clarifies, “data scientists typically need at least a bachelor’s degree in mathematics, statistics, computer science, or a related field to enter the occupation.”
However, if you do a quick Google search, you will also find that there are a number of data science “bootcamp” programs that claim to cover the essential skills you need to enter the field as well.
Degree Programs vs. Bootcamps: What Is Right for You?
For some, the appeal of a data science bootcamp is that it could typically be completed in a much shorter timeframe than a formal degree program. However, it is important to understand that, unlike formal degree programs, bootcamps often do not lead to a traditional academic designation or degree.
