Whenever I've thought of data science, the first question that echoed in my mind was, "Where do I even begin?"

The Internet is filled with resources, each promising to be the golden ticket to mastering data science. But the abundance of choices becomes more of a puzzle than a solution.

Do I need a formal education in Data Science, or can I teach myself online? Should I start with programming languages like Python or dive into statistics? Should I focus on theory or practical applications? The "how" of getting started was bewildering. The more I tried to research and answer these questions, the more confused I became.

The fear of drowning in complex technicalities looms large, and I longed for a guide that spoke my language – simple, clear, and devoid of unnecessary jargon.

Reflecting on those initial moments of confusion, I realized that many novices like me struggle with similar concerns. The struggle to decipher where and how to start with Data Science is a universal experience for beginners. 

In this blog, I aim to clarify the confusing aspects of data science by addressing the fundamental questions that cloud the minds of beginners.

So, here we go!

Question 1: What is data science course?

A data science course is like a guide that teaches you how to handle and make sense of data. It's a set of lessons or classes that teach you the skills and tools needed to collect, analyze, and draw useful insights from different kinds of information.
