Common Questions Beginners in Data Science ask

  • I have no programming experience. Would I need to learn Python to learn data science?

    Programming is an essential aspect of being a data scientist or a data science professional. And Python is the market leader in this space. Organizations globally are adopting Python as their go-to language, including big tech firms like Spotify, Netflix, Facebook, among others.

    Python consistently ranks top in global data science surveys and its widespread popularity will only keep on increasing in the coming years.

    Over the years, with strong data science community support, this language has obtained a dedicated library for data analysis and predictive modelling.

    And don’t worry! Python is a very easy language to learn and we cover it from scratch in the course. So you don’t need to have any prior programming knowledge to master Python!

  • Do I need to know statistics before taking this course?

    No! Statistics is the backbone of data science and we understand that. We have designed an entire comprehensive module on statistics which we cover in the course.

    We will cover both descriptive statistics and inferential statistics in detail, along with how to implement each concept in Python. And once you’ve learned and practiced statistics concepts, we will then jump to data science modelling.

  • What kind of projects can I take up after this course?

    You can take up a variety of data science projects! Since this covers both regression and classification algorithms, like linear regression, logistic regression and decision trees, you’ll be well equipped to apply your data science and Python skills on real world projects.

    We recommend you pick up the projects we’ve curated on the DataHack platform. These projects will hone your data science skills and enhance what you have learned in the Introduction to Data Science course.

  • Can I add the projects covered in this course in my resume?

    Of course! Projects are among the first things a hiring manager or recruiter looks for in a data science resume. The more projects you add, the stronger your chance of landing your dream role.

    As mentioned above, you can head to the DataHack platform and pick up projects from there. Practice is key in data science!

  • Will this course help me clear data science interviews?

    This course will help you build a solid base for data science. You will learn a new programming language (Python), the backbone of data science (statistics), and core predictive modeling techniques.

    As a next step, you should go through our course - Ace Data Science Interviews.

    I really loved this course, everything is explained in detail by all the instructors. Multiple lessons in a module, in between MCQs, regular assignments, each implementation lesson is provided with the materials used in the video, jupyter files, and the datasets. Before this course, I didn't know a single thing about Data Science but now I have ample knowledge about how to work on real-life problems in Data Science. Thanks to every instructor. Looking forward to enroll in more courses by Analytics Vidhya.
