The principles of validity and reliability are fundamental cornerstones of the scientific method.In general, VALIDITY is an indication of how sound your research is.
To understand the traditional definition of construct validity, it is first necessary to understand what a construct is.The type of validity assessed in this example is that of construct validity.
Establishing Validity of Experimental Studies - MedscapeInstrumentation --Changing the measurement methods (or their administration).The performance of subjects in some studies is more a product or reaction to the.Reliability and validity are two desirable qualities of any measurement procedure or instrument.Discuss the need to balance control and generalization when performing research.Reproduction or retransmission of the materials, in whole or in part.Perhaps, like Sarah, the goal is to generalize to the population as a whole, based on an experiment done on a small sample of the population.

Validity: the best available approximation to the truth of a given proposition, inference, or conclusion.Generalization OK, you might be thinking, so just make sure that every study has a whole lot of external validity.
