The elements of production typewriting, including production time and production quality, for the first-time typing of business letters originated by machine dictation and longhand and typed on correcting electric and text-editing typewriters, were analyzed. Students typed four business letters, one under each of four conditions: on the correcting electric from machine dictation, on the text-editing from machine dictation, on the correcting electric from longhand, and on· the text-editing from longhand.

Analyses were done for the elements of production time and for the elements of production quality. A two-factor ANOVA in a randomized block design was used to analyze the data for types of equipment when methods of origination were pooled and for methods of origination when types of equipment were pooled. When types of equipment and methods of origination were examined separately, the model was a randomized block design.

Analyses of the elements of production time showed that (1) students took longer to produce copy when they typed on the text-editing typewriter than when they typed on the correcting electric typewriter and (2) students took longer to produce copy when they transcribed from machine dictation than when they transcribed from longhand.

Analyses of the elements of production quality showed that students made more errors when they transcribed from machine dictation than when they transcribed from longhand.
