Plot data for visual checks

The complete dataset is available for visualisation below. Labels of extreme outliers were visually displayed on the graphs for manual checks of the data. The following plots provide a comparison of the dataset with and without outliers to appreciate the (relative absence of) effect of these.

Statistical modelling

Below are box plots of the data, and the fitted data by the statistical model, which is provided as the formula below:

Value ~ SessionName + SubjectGroup/Side + SessionName:SubjectGroup + WSpeed + (1|SubjectStudyID)

The model generates the following table
