What Does a Data Scientist Do?

A data scientist studies complex datasets with statistical methods, machine learning algorithms, and programming skills to gain meaningful insights from the data. They digs out patterns, trends, and correlations for the organization to make better decisions, develops predictive models, and addresses tough problems across various domains. Hence, organizations require Data Scientists to store, analyze, and manage big chunks of structured, semi-structured, and unstructured data.
