Final answer:
The appropriate dashboard type for data that does not change frequently is a static dashboard, which is considered nonreactive and suits non-dynamic data presentation.
Step-by-step explanation:
When the data on which the dashboard is based do not change frequently, the appropriate type of dashboard to use is a static dashboard. A static dashboard displays data that does not update automatically and is suitable for reporting on information that does not require real-time or frequent updates.
This contrasts with dynamic or interactive dashboards, which are designed to display frequently changing data and often allow users to interact with the data, such as filtering views or drilling down into more detailed information.
Using secondary data for such a static dashboard is considered an unobtrusive method of research, often referred to as nonreactive, as it does not involve direct interaction with the subjects of the data. A dynamic dashboard is appropriate when the data on which the dashboard is based do not change frequently.
Therefore answer is b. Static dashboard.
