What is the role of a data scientist?

The role of a data scientist is to apply statistical, machine learning, visualization techniques, and analytic approaches to answer critical business questions. Data scientists are responsible for identifying and analyzing large and complex data sets, building predictive models, and generating insights to inform business decisions. They use a range of tools and techniques, including statistical analysis, data mining, machine learning algorithms, and data visualization, to extract meaningful insights from data. Data scientists are often involved in building and optimizing data pipelines for collecting and organizing data, as well as deploying models into production environments. While data cleaning is an important task, it is usually performed by data engineers or data entry specialists rather than data scientists.
