The Answer is Sound business research requires that the researcher plan and establish a design for the experiment before a study is undertaken.The design of the experiment should encompass the treatment variables to be studied,manipulated,and controlled.These variables are often referred to as the independent variables.It is possible to study several independent variables and several levels,or classifications,of each of the variables in one design.In addition,the researcher selects one measurement to be taken from sample items under the conditions of the experiment.This measurement is referred to as the dependent variable because if the treatment effect is significant,the measurement of the dependent variable will "depend" on the independent variable(s)selected.In this chapter,we explored three types of experimental designs: completely randomized design,randomized block design,and factorial experimental designs.
