The following questions address a number of key design features that must be considered. To minimise the variability effect on the result of interest, the experiment has to be designed. The design and analysis of an experiment are best considered as two aspects of the same enterprise: the goals of the analysis strongly inform an appropriate design, and the implemented design determines Know that the answer to Experimental Design questions will always be buried within the passage. A hypothesis is a proposed explanation of an observation based on limited evidence. By an experiment we understand an investigation where the researcher has full control over selecting and altering the experimental conditions of interest, and we only consider investigations of this type. By solving the Question Papers, you can scale your preparation level and work on your weak areas. What are the key principles of experimental design? Control: Minimizing the influence of extraneous variables to isolate the effect of the independent variable. So, the researcher will design the experiments for the purpose of improvement of precision. The choice would be determined by (a) the nature of treatments (treatments structured or unstructured); (b) variability in the experimental units and the way it is accounted for; (c) questions to be answered or inference problem. For our purposes here, we use the term “experimental” to refer to designs that feature two essential ingredients: first, manipulation of an independent variable; and second, random assignment of subjects. , 1978), is represented by a The position and size of the window depend on the questions being asked by and the quality of the experiment.
