Frequently Asked Questions
What is the best way to start learning Data Science?
A combination of theoretical study and practical application is best. Start by learning a programming language like Python or R, and the basics of statistics. Then, apply what you learn by working on projects, such as analyzing public datasets from Kaggle. Supplement this with online courses or tutorials from the channels listed here.
Should I learn Python or R for Data Science?
Both are excellent choices. Python is generally recommended for beginners due to its simple syntax and versatility, especially if you want to move into Machine Learning or Deep Learning. R is a powerhouse for statistical analysis and academic research. Many professionals end up learning the basics of both, but Python is currently more dominant in the industry.
Do I need a strong math background to become a Data Scientist?
While a degree in mathematics isn't strictly necessary, a solid understanding of certain mathematical concepts is crucial. Focus on Probability, Statistics, Linear Algebra, and Calculus (specifically derivatives and gradients for optimization). You don't need to be a mathematician, but you need to understand how algorithms work under the hood.
What kind of projects should I include in my portfolio?
Aim for a diverse mix of projects that showcase different skills: an Exploratory Data Analysis (EDA) project to show your storytelling ability, a Machine Learning project to demonstrate your modeling skills, and perhaps a deployed app (using Streamlit or Flask) to show you can put models into production.
