Factors Affecting Experimental Design:
(1) Element of time: Experimental design is time consuming Planning experimental design takes lot of time because the researcher has to consider pros and cons of various design available to him
(2) Commitment of management: Experimental design needs high level of management commitment If management becomes disheartened with any experiment and it is allowed to lapse without running its full course or is handled half-heartedly, all efforts will be wasted
(3) Range of variation: Under proper condition, experimental design can indicate the effects of specific variations in one or more elements of the marketing mix The experiment can be done with only one variable like price or with multiple variables like colour of packaging, channel of distribution and sales promotion
(4) Cost and accuracy: Experimental design must balance cost constraints with accuracy. Accuracy is related to the amount of error We should not assume that the possibility of an experimental error means that the error will occur The cost of running experimental design should be less and benefits obtained should be more (5)
(5) Identification of variables: Experimental design uses one or more variables in such a way that its effect on one or more variables can be measured Hence it becomes necessary to identify the variables correctly
