The concepts of objectivity, reliability, validity and generalisability provide a basic framework for conducting and evaluating traditional quantitative research. External validity: the validity of inferences about whether the cause effect relationship holds over variation in persons, settings, treatment variables, and measurement variables. When trying to show that an assessment tool or a data collection tool or a service delivery tool is useful, the characteristics of validity and reliability are generally used to make that argument. a valid tool is one that does what it is supposed to do or measures what it is sup posed to measure. A simple example of validity and reliability is an alarm clock that rings at 7:00 each morning, but is set for 6:30. it is very reliable (it consistently rings the same time each day), but is not valid (it is not ringing at the desired time).
