Observation Oriented Modeling is a novel approach towardconceptualizing and analyzing data. Compared with traditional parametric statistics,Observation Oriented Modeling is more intuitive, relatively free of assumptions, andencourages researchers to stay close to their data. Rather than estimating abstractpopulation parameters, the overarching goal of the analysis is to identify and explaindistinct patterns within the observations. Selected data from a recent study by Craig etal. were analyzed using Observation Oriented Modeling; this analysis was contrasted witha traditional repeated measures ANOVA assessment. Various pitfalls in traditionalparametric analyses were avoided when using Observation Oriented Modeling, including thepresence of outliers and missing data. The differences between Observation OrientedModeling and various parametric and nonparametric statistical methods were finallydiscussed
