FAQs

Can I transition into data science without a technical degree?

Yes, many professionals move into data science from non-technical backgrounds. It may take extra effort to learn programming, statistics, and analytical thinking, but online courses and bootcamps make this transition possible.

What’s the difference between a data analyst and a data scientist?

A data analyst focuses more on interpreting historical data to provide insights, while a data scientist builds predictive models and works with more advanced algorithms to forecast future trends. Both roles are important, but the scope and complexity differ.

How long does it usually take to become job-ready in data science?

This depends on your starting point and learning speed. For beginners, it can take 6–12 months of consistent study and practice to be job-ready, while those with some technical background may take less time.

Are free data science courses worth it?

Free courses can be a great starting point to explore the basics and see if the field interests you. However, for advanced skills and recognised credentials, paid programs often offer better structure and support.

Can internships really help in starting a data science career?

Yes, internships offer hands-on experience, industry exposure, and a chance to apply your learning in real-world situations. They also strengthen your resume and can lead to full-time job offers.

Is coding the only skill I need for data science?

No. Coding is essential, but you will also need statistics, data visualisation, problem-solving, and communication skills to truly excel in the role.
