What Is Data Science?

Before talking about courses and careers, let’s understand Data Science in simple words.

Data Science Course in delhi is the process of using data, statistics, programming, and technology to find useful information and solve real-world problems.

For example, imagine an online shopping website. It has thousands of customers and millions of transactions. The company may want to know:

• • Which products are selling the most?

• • What are customers likely to buy next?

• • Why are some customers leaving?

• • How much stock should be kept?

• • Which customers are more likely to respond to an offer?

Data Science can help answer these questions.

To do this, professionals use programming languages such as Python, databases such as SQL, statistical techniques, Machine Learning algorithms, and visualization tools.

Therefore, Data Science is not just about numbers or coding. Instead, it combines technology, analysis, and business thinking.
