Introduction Sample simulator GUI for multiple repertory grid studies. A common approach for evaluating multiple repertory grids is to sort the elicited constructs into categories using content analysis (e.g. Green, 2004; Jankowicz, 2004). Sometimes the question arises what sample size would be needed in order to achieve a minimum saturation of a certain number of constructs per category. The gridsampler GUI allows to run simulations in order to answer these type of questions. References Green, B. (2004). Personal construct psychology and content analysis.
