| Description | In the experiments described in Chapters 2 through 4, the purpose was to compare the response between different levels of controllable variables or factors in order to predict what the response might be in the future at specific levels of the factors, or to recommend the best factor level for future use. Another purpose of experimentation is to study sources of variability in the response. For example, cholesterol, blood glucose, and other diagnostic tests made by doctors are known to vary with the procedures and the equipment used to make the measurements. Experiments might be conducted to find out how much of the variability is due to equipment and how much is due to procedure. Symbolically σ2T = σ2p + σ2e where σ2T is the total variance, σ2p and σ2e are the portions of the total due to procedure and equipment, respectively. σ2p and σ 2 e are called the components of variance or variance components. An experiment can be conducted to collect data so that the variance components can be estimated. In this type of experiment, there might not be any interest in the difference in average diagnostic readings between specific pieces of equipment because there are (and will continue to be) many in use.
