What Is Data Science? 

Data science is a field that involves extracting information and knowledge from large amounts of data. It combines various techniques, such as statistics, mathematics, and programming, to uncover patterns, trends, and relationships within data. Data scientists use tools and algorithms to analyze data and provide valuable information to inform decision-making and drive improvements in various domains, including business, healthcare, and technology.

In other words, data science is like being a detective for data. It’s about collecting and examining large sets of information to find hidden patterns and make sense of it all. Data scientists use their skills to ask questions, explore data, and use different methods to uncover helpful information that can help solve problems or make informed predictions. They are crucial in turning raw data into actionable knowledge that can lead to better outcomes and innovations.
