Which type of node is primarily used to gather and manage data in SPSS Modeler?

The Source Node is primarily used to gather and manage data in SPSS Modeler. This type of node serves as the entry point for data into a modeling stream. It can connect to various data sources such as databases, spreadsheets, or flat files, allowing users to import data into the environment for analysis.

Once the data is brought in through the Source Node, it can then be processed and transformed by other nodes in the stream, such as filtering, data cleansing, and applying models. This foundational role of the Source Node is crucial, as it sets the stage for subsequent data manipulation and analysis. Without this node, the modeler would lack the data necessary for effective predictive analytics.

Understanding this crucial function helps in effectively constructing workflows in SPSS Modeler, ensuring that data is accurately sourced and prepared for analytical tasks.
