Abstract

The arithemetical procedure known as the analysis of variance is offered as a method determining the reliability of a test when two forms are given to subjects of known differences in ability or determining proficiency of students when given scaled questions. Results obtained by members of the English Department of Iowa State College in the process of designing a progress test are used as an example. The students were divided into high and low groups on the basis of scores received previously on the Iowa State College aptitude test, on a theme and on the Iowa State College English Department placement test. Three sources of variability are tested, namely: form, time and students. Complete details of the method are presented using the English Department data.
