Frequently Asked Questions
What is Data Science in simple words?
Data Science is the practice of using data, statistics and code to find patterns and answer business questions. In simple words, a data scientist looks at large amounts of data and figures out what it means and what to do next.
What skills do I need to learn Data Science?
You need Python programming, basic statistics and probability, SQL for databases, data visualization tools, and machine learning fundamentals. NextVision Infotech's Data Science with Python course covers all of these in a structured 2-month program.
How long does it take to learn Data Science?
A beginner can learn job-ready Data Science basics in 2-3 months with focused, project-based training. Becoming an expert takes longer practice, but our course gets you to a working, portfolio-ready level in 2 months.

Entry-level Data Science roles in India typically start around ₹3-6 LPA, with experienced professionals earning significantly more. Salary depends on skills, portfolio projects, and the city/company you work with.
Is a Data Science course worth it in 2026?
Yes -- Data Science remains one of the most in-demand skills across IT, finance, healthcare and e-commerce in India. A structured course with real projects (not just theory) is worth it because employers look for practical Python and analysis skills.
Data Science vs Data Analytics -- what is the difference?
