WebExperimental design is the process of carrying out research in an objective and controlled fashion so that precision is maximized and specific conclusions can be drawn regarding a hypothesis statement. Generally, the purpose is to establish the effect that a factor or independent variable has on a dependent variable. http://campus.murraystate.edu/academic/faculty/kfister1/Current/135DeVeaux4Ch11Spring2015.pdf
