Data science is an interdisciplinary academic field that uses statistics, scientific computing, scientific methods, processes, scientific visualization, algorithms and systems to extract or extrapolate knowledge and insights from potentially noisy, structured, or unstructured data.
Data scientists are responsible for collecting, cleaning, and analyzing large datasets to extract valuable insights and make data-driven decisions. They use various machine learning and statistical techniques to build predictive models and solve complex problems.

Skills that you need to excel in Data science

There is a variety of skills a new professional in data science would need to equip themselves with. These include:
