An observational study can be defined as a type of study in which a researcher observes and measures the effect of a diagnostic test, risk factors, or treatments on individuals without intervening, changing or manipulating who are or aren't exposed to it (controlled conditions).

Basically, observation is a research method that involves examining a given population in order to gather certain informations about them. Thus, it is typically aimed at observing the activities that are being performed by a population of interest.

Hence, measuring how many parts workers assemble in an hour would be considered to be an example of gathering data by observation because you would have to monitor and keep an eye on the workers as they perform their jobs.
