What is difference between data analysis and data science

Data analysis and data science are two related but distinct fields. Data analysis is the process of inspecting, cleaning, transforming, and modeling data to extract insights and make informed decisions. It is focused on using statistical methods to understand and summarize data.

Data science, on the other hand, is a broader field that encompasses data analysis but also includes other skills such as machine learning, computer science, and domain expertise. Data scientists are responsible for developing and applying algorithms to extract insights and knowledge from structured and unstructured data. They use a variety of techniques to extract patterns, predict outcomes, and make data-driven decisions.

In essence, data analysis is a subset of data science. Data analysis focuses on the statistical methods used to extract insights from data, while data science encompasses a broader range of skills and techniques used to extract insights, including machine learning and computer science.
