Spurious Precision – Leading to Evaluations that Misrepresent and Mislead by Burt Perrin
Sometimes it is helpful to be very precise. But, in other cases, this could be irrelevant at best, and quite likely misleading. And destroy, rather than enhance, the credibility of your evaluation – and of you. Hi, I’m Burt Perrin, and I’d like to discuss what considerations such as these mean for evaluation practice.
