Validity :it is a measurement tool used in research methodsit measures what it claims to measure. Construct validity entails demonstrating the power of such a construct to explain a network of research findings and to predict further relationships the more evidence a researcher can demonstrate for a test's construct validity the better however, there is no single method of determining the construct validity of a test instead. Validity research validity in surveys relates to the extent at which the survey measures right elements that need to be measured in simple terms, validity refers to how well an instrument as measures what it is intended to measure reliability alone is not enough, measures need to be reliable, as well as, valid for example.

Triangulation is a commonly used method for verifying accuracy that involves cross-checking information from multiple perspectives the link in resources links on the left describes different types of triangulation methods transferability - often called external validity, refers to the degree that the findings of the research can. In order for research data to be of value and of use, they must be both reliable and valid validity validity refers to the credibility or believability of the research are the findings genuine is hand strength a valid measure of intelligence almost certainly different methods vary with regard to these two aspects of validity. External validity is the extent to which the results of a study can be generalized from a sample to a population checks, peer evaluation (another researcher checks the researcher's inferences based on the instrument (denzin & lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used.

How the terms are used inside and outside of research outside of statistical research, reliability and validity are used interchangeably the term “reliability coefficient” actually refers to several different coefficients: several methods exist for calculating the coefficient include test-retest, parallel forms and.
