ABSTRACT: What we call research is argued by authorities as “not fact-finding”, and such authorities further their argument that “when you don’t know and you carry out investigation in order to know it is not research but fact finding”. That research, is (only) a study designed to fill a gap in human knowledge (Awokeni, 2001)wherever this argument goes the fact remain that in management sciences whenever a problem exists and needed to be solved, a search and/or further search has to be conducted to gather knowledge in order to solve such problems. But since management problems are social problems, social research is essential and this entails studying a collection me objects individuals and events. Most times this collection of individuals for study are large that studying them would not make sense hence use of samples drawn from the collection.
