Day to day tasks of a Data Scientist
Data Scientist definition
A data scientist is a highly trained individual who is mostly technical but also able to interrupt data in a business manner. Data scientists are required to interpret a lot of complex data. To do this, they employ techniques like machine learning, algorithms, and various types of modelling to identify patterns in the data. Once they have identified patterns in both structured and unstructured data sets, they are required to action such data in ways that help the business.
