A factual survey is a survey based solely upon factual and verifiable input it does not consider variables of what might occur should things be different in an assumptive or hypothetical situation. For example a factual survey is used to determine the speed limit on a neighborhood street. Evidence is gathered by clocking the speed of a number of motorist's on that roadway over a specific period of time and a mathematical equation is applied to determine the speed limit. An assumptive survey would weigh in factors of . What ifs such as " What if a a shopping mall were to open on that roadway?
