Definición Objectivity

Objectivity is an important criterion during data ascertainment. Basically, it means that a method of data collection must always come to the same result, regardless of who ascertains the data. So whether interviewer A or interview B conducts a survey should not make any difference. Similarly, when conducting an observation, the documentation must be carried out in the same fashion by all parties; the same goes for the execution and management of an experiment.

Other important quality criteria for scientific studies are reliability and validity.
