The used of Experimental Designs in Social research with the Subjects

Design of Experiments (DOE) is one of most usable methods in hypothesis tests of a research. Nowadays we define it one of original. tools in produce procedures control and test of suggestions to more revenue and going to distinct desirability. This subject is especially useful for agricultural engineering. this same engineering studies impelling to DOE abilities causes we think this is a technique for product engineering studies، while useful for another areas that one of them is social science. This paper investigates Design of Experiments ability in social science especial police missions. Therefore we describe some methods in DOE with usefully instances، like complete block design، stratified design.
