| Summary |
"Since its introduction by R.A. Fisher in 1923, analysis of variance has proved itself a useful addition to statistical methods. It is a technique for segregating from comparable groups of data the variation traceable to specified sources. It furnishes an estimate of experimental error freed of that part of the variability whose origin is known. In conjunction with an associated test of significance, it affords a basis of judgment as to whether or not several groups are samples from a single homogeneous population. Through the use of degrees of freedom it is equally well adapted to the treatment of large or small samples. It lends itself readily to the design of efficient experimental procedures, and to tests of experimental technique. In the analysis of covariance, the method is extended to include two or more associated variables. The method of this monograph is to present in simple fashion a group of successful applications of analysis of variance and covariance. Explanations of the processes of calculation and the results obtained are rather copious. Interpretations are necessarily limited, but may usually be found in the references cited. At the first reading, sections entitled "Computation" and "Notes on theory" may well be omitted. The "Computation" sections contain complete instructions for calculation"--Introduction.
