1. What is a Data Science course?

Mathematics, business acumen, tools, algorithms, and machine learning techniques are all used in data science to uncover hidden patterns or insights from raw data that can inform the formation of major business decisions.

One has to work with unstructured and structured data in data science. Predictive analytics is also a part of the algorithms. Data science is, therefore, about the present and the future. This means finding trends based on historical data that can be useful for present-day decisions and finding patterns that can be modeled and used to predict what things might look like in the future.

Data Science is a combination of Statistics, Tools, and Business knowledge. Therefore, Data Scientists need to have good knowledge and understanding of these topics.

Data Science Components

Data Science Components
