The Most In-Demand Data Science Skills Taught in Courses

The growth forecast for the global market for big data is predicted to be CAD 379.9 billion by 2026. Compared to 2018, this represents over 200% growth, establishing big data as a big business. Despite the growing demand, there is a shortage of qualified data professionals worldwide, and this is where learning data scientist technical skills can help students progress far in their careers.

Skill	Importance
Python	One of the most popular programming languages in the world.
R	Extremely important for computing and statistical analysis.
Math and Statistics	Necessary for career development.
SQL	Important for communicating with and managing relational databases.
NoSQL	Essential for working with unstructured data.

Python

Python is one of the world’s most prominent programming languages, making it the most important of all data science skills required. The language ranks first on several popularity indexes, such as the PYPL Index and the TIOBE Index. A significant reason why Python is so popular is its suitability for data analysis work. An interesting thing about Python is that even though it was not created for data science, it has evolved over the years and become the king of the industry.

R

R is the queen of data science and the king of Python. Since its inception in 1992, R has been an open-source programming language specializing in computing and statistical analysis. It is widely used in academia, scientific research, and sectors like business and finance. A significant benefit of R is that it permits various data analyses.

Math and Statistics

Having a mathematical background is not one of the most essential data scientist skills. However, students must be familiar with a few statistical and mathematical concepts to progress well in this domain. They must also have a firm grip on statistics when selecting and applying the various data techniques. Such skills also help with constructing strong data models and understanding data properly.

SQL

SQL has existed since the 1960s, and data scientists still need to learn it to do their work properly. SQL is a standard industry tool for communicating with and managing relational databases, which lets structured data be stored in tables related to some common columns.

NoSQL

NoSQL helps deal with unstructured data, making it one of the most critical data science skills. The ability to deal with unstructured data is essential because coping with unstructured data can be significantly more complex than dealing with structured data. Most of the data generated these days is unstructured and comes from sources such as:

Audio
Video
Satellite images
Web server logs

The unstructured nature of such data makes it hard to process and store using conventional relational models.
