I was sitting before my TV set, a while back, watching Captain Video and pondering the organizational problems of psychologists, psychometricians, psychodiagnosticians, psycho-somatists, psychosomnabulists, and psychoceramics (crack-pots to you). Wondering what I might do, in my small way, to help out, I decided to enlist Captain Video's help to bring me from the Black Planet that superogalactian hypermetrician, Dr. Idnozs Hcahscror-Tenib, cosmos-famous discoverer of Serutan. Why delay? The Galaxy was on its way. and in half a light year Dr. Tenib was at my side prepared to devote his gargantuan talents to the task. Seeing no point in confusing the good doctor by trying to describe to him the present administrative hodgepodge, I said," Doctor, let's start from scratch. I want you to find out for me how these good people who are present at the annual meeting of the APA structure themselves? What families are represented? How many, or better, how few? And who belongs to each?"" We proceed," said the Doctor." Bring sample of population; I measure." So we set out to design a sample. The problem presented some interesting theoretical aspects, but the final solution was relatively simple. We stationed representatives at each of the three state beverage stores and followed every third badge-wearing individual who came out of a store. We selected only outgoing patrons for obvious reasons.
