Switching to Data Science: Skills to Anticipate


Switching to a career in data science requires combining technical and non-technical skills. Technical skills are required to apply data science skills while non-technical skills are required to identify where best to apply those skills.  One needs to pursue a well-organised Data Science Course to acquire these diverse skills.  So also, while some skills are basic and needed for applying data science at any level, some skills are advanced or domain-specific. Following is a brief description of the skills one should anticipate to acquire in switching to data science.

The Basic Skills

Data science is a complex and vast technology area and the skills in this area that one needs to acquire depend largely on the industry or business segment where the skills must be applied, and on individual aspirations such as whether to pursue a technologist’s role, a researcher’s role, or a developer’s role. This is the reason that there is a proliferation of data science programs that package different skill sets. Thus, a Data Science Course in Delhi might offer, in addition to the regular topics that form part of any course, a host of topics from which one can choose. However, some  skills are imperative for gaining a reasonable grasp of this advanced branch of technology. Some of these are listed and briefly explained here.

  • Programming Skills: 

Python or R: Both Python and R are used in data science for data manipulation, analysis, and modelling. Learning either of these languages is essential. These programming languages generally form part of any Data Science Course.

  • Statistical and Mathematical Proficiency:

A solid foundation in statistics and mathematics is crucial for understanding and building machine learning models.

  • Data Manipulation and Preprocessing: 

Proficiency in data cleaning and preprocessing techniques to handle missing data and outliers and prepare data for analysis.

  • Machine Learning: 

Understanding of various machine learning algorithms (such as regression, classification, clustering) and the ability to implement them.

  • Data Visualisation: 

Knowledge of data visualisation libraries and tools (to communicate insights effectively.

  • SQL and Database Management: 

Ability to work with relational databases and write SQL queries for data extraction and manipulation. This is a crucial skill and forms part of the course, whether you enrol in a Data Science Course in Delhi or in any other city.

  • Version Control: 

Proficiency in using version control systems like Git to collaborate on projects and track changes.

  • Data Ethics and Bias Awareness: 

Understanding of data ethics, privacy, and bias mitigation to ensure responsible data handling and modelling.

  • Problem-Solving Skills: 

The ability to break down complex problems into manageable tasks and develop creative solutions.

  • Communication Skills: 

Effective communication is crucial for explaining complex findings and insights to non-technical stakeholders. Although considered a soft skill, an inclusive Data Science Course will have some focus on enhancing the learner’s communication skills.

  • Project Management: 

Basic project management skills to effectively plan, execute, and deliver data science projects.

  • Continuous Learning: 

A willingness to stay updated with the latest developments in data science through courses, workshops, and self-study.

  • Portfolio Building:

Creating a portfolio of data science projects that showcase relevant skills and demonstrate problem-solving capabilities.

  • Networking: 

Building connections within the data science community can help you learn, find job opportunities, and collaborate on projects.

  • Resilience and Adaptability: 

The data science field is constantly evolving; adaptability and a willingness to embrace change are essential.

Specific Skills

Because the applicability of data science is fast becoming relevant across business segments and verticals, there is a need for building skills that are domain-specific.  Professionals who want to advance in their careers are the ones who typically look for these skills. These skills are offered based on demand patterns and tend to vary with location and in response to market dynamics. A data science course in Delhi or in a similar industrial centre or technological hub might offer such specific training modules as electives that form part of a main course or as more elaborate standalone modules. Some of these skills are:

  • Big Data Technologies: 

Familiarity with big data frameworks like Hadoop, Spark, and NoSQL databases is needed for those working with large datasets.

  • Deep Learning: 

For deep learning, proficiency in neural networks and frameworks like TensorFlow or PyTorch can be beneficial.

  • Domain Knowledge (industry-specific): 

Domain-specific knowledge can be highly valuable depending on the industry you plan to work in or already work in. 


To acquire these skills, consider enrolling in a data science boot camp, pursuing a formal degree in data science or a related field, taking online courses, participating in hackathons or competitions, and working on personal projects. The versatility of data science is such that even the skills that a basic Data Science Course will provide can make for a successful transition to a career in data science.
