What Does a Data Scientist Do?

Researchers are developing models to forecast future outcomes, and are analyzing massive datasets. This data is used in many different industries and areas of work such as healthcare, transportation (optimizing delivery routes) and sports, e-commerce finance, and many more. Data scientists can employ many tools for their work, like Python or R, machine-learning algorithms, as well as data visualization software, based on the specific domain. They also develop reports and dashboards to communicate their findings to business executives as well as other non-technical employees.

Data scientists must understand the context of the data collection to make the right analytical decisions. That’s one of the reasons why no two data scientist jobs are identical. Data science is heavily influenced by the organizational objectives of the process or business.

Data science applications require special tools and software. For example, IBM’s SPSS platform comes with two main products: SPSS Statistics, a statistical analysis tool, data visualization and reporting tool as well as SPSS Modeler, a predictive modeling and analytics tool that features a drag-and-drop UI and machine learning capabilities.

To speed up the production of machine learning models, companies are advancing the process by investing in platforms, processes, methods, feature stores and machine learning operations (MLOps) systems. They can then deploy their models faster and find and fix any errors in the models, before they result in costly errors. Data science applications frequently need to be updated to keep up with changes to the data that underlie it and the changing needs of business.
