What Does a Data Scientist Do?

Researchers are developing models to forecast future outcomes, and are analyzing massive datasets. Data science is used in various sectors and industries, such as healthcare (optimizing delivery routes), transportation (optimizing routes optimization) sports, ecommerce, finance, etc. Based on the field that they are working in, data scientists could employ math and statistical analysis skills, programming languages like Python or R, machine learning algorithms, as well as tools for visualizing data. They also create dashboards and reports that communicate their findings to business executives as well as other non-technical employees.

Data scientists must understand the context of data collection in order to make informed decision-making based on analysis. That’s one of the reasons why no two data scientists’ jobs are the same. Data science is a lot of a reliant on the goals of the business or process.

Data science applications require specialized hardware and software. For example IBM’s SPSS platform features two primary products: SPSS Statistics, a statistical analysis, data visualization and reporting tool as well as SPSS Modeler, a predictive modeling and analytics tool that has a drag-and drop interface and machine learning capabilities.

To speed up the creation of machine learning models, companies are industrializing the process by investing in platforms, processes and methodologies, feature stores, and machine learning operations (MLOps) systems. They can then deploy their models quicker and find and fix any errors in the models, before they cause costly mistakes. Data science applications often need to be updated to accommodate changes in the data that they are based on or to meet changing business requirements.
