In research, the ecological validity of a study means that the methods, materials and setting of the study must approximate the real-world that is being examined. Unlike internal and external validity, ecological validity is not necessary to the overall validity of a study.
A reliable instrument produces consistent results regardless of the setting, yet reliability does not ensure accuracy or validity. Validity refers to an instrumentâs capacity to accurately measure what the researcher intended to measure. Reliability must be accompanied with validity regarding an instrument worthy of use in conducting doctoral research. A few simple examples help explain the meaning of reliability and validity.
