N2  - Researchers conducting participatory on1arm trials, particularly variety selection trials, often have difficulty analyzing the resulting data. The irregularity of trial designs means that some of the standard tools based on analysis of variance are not appropriate. In this paper some simple extensions to analysis of variance, using general linear models and linear mixed models, are shown to facilitate insightful analysis of these awkward designs
