Basic Notions of Data Analysis
Having designed the experimentation, each unitary experiment is run as prescribed by the design. Measurements of the response variable are taken during the experiments. So, after completing the unitary experiments, experimenters have a collection of data, called the results of the experimentation. By examining or analysing these data, experimenters will arrive at conclusions about the relationships between factors, the influence of factors on the response variables and the alternatives that improve the values of the response variables. The data analysis branch of statistics provides the techniques for examining the experimental results. These are statistical methods that are used to analyse the data output by experiments and are explained in this, the third part of the book.
