Mostly, they have to work with indirect measurements, like watching for slight dips in the intensity of a star's light when a planet passes in front of it, a phenomenon known as a transit.But if indirect observation is all that is on offer, then astronomers must make the best of it.
This is a very different approach from the indirect observation on which most companies rely reports, interviews, surveys, narratives, aggregate data, and statistics.

Initially, an indirect clinical observation was made to determine the skull pattern (dolichocephalic, mesocephalic or brachycephalic), based on visual equivalence of right eurion- left eurion and glabella-opisthocranion anthropometric points, as well as the facial type (leptoprosopic, mesoprosopic and euryprosopic), according to the left and right zygomatic, nasion and gnation points.
