Power BI Reports often contain parameters in the form of filters and slicers.
These are parameters a user can use to slice and dice to find only the desired data in a report.
Some slicers allow you to select all options (usually long lists) and some only allow you to select one option at a time.
In general filters should keep their values from page to page of a report.
Filters will also be persistent once set for every time you login. That means that if you set a Career filter to show Undergradaute, that will remain set at Undergraduate even if you leave the website and come back. All filters will have this behavior, and can be rest using the rest button.
