experimenter's

Belonging to investigator

Experimenter's is the possessive form of experimenter—someone who conducts experiments.

It typically modifies nouns related to research methodology: the experimenter's hypothesis, the experimenter's bias, the experimenter's instructions to subjects.

In psychology, experimenter's bias or experimenter's effect refers to ways a researcher's expectations can inadvertently influence results.
