Statistical conclusion validity assesses the mathematical relationships that exist between variables and makes inferences about whether this statistical formulation correctly expresses the true co-variation. This validity deals with the quality of the statistical evidence of co-variation such as sources of error, the use of appropriate statistical tools, and bias. Type I and Type II errors are classic violations of this kind of validity.The article by David and Joseph tries to establish a method for investigative the cognitive processes and knowledge structures of expert salespeople.
