From: Comparing DTL microfiber and Neuroline skin electrode in the Mini Ganzfeld ERG
Box plots of the light-adapted 3.0 responses. a depicts box plots of the a-, and b-wave amplitudes, whereas b depict box plots of the a-, and b-wave implicit times recorded with both electrode types. For all box plots, recordings obtained with a DTL electrode are plotted to the left, while recordings obtained with a Neuroline skin electrode are plotted to the right. The box length is the inter-quartile range. The line in bold depicts the median. Values between 1.3 and 3.0 box length represent outliers (open circles) and those with values more than 3.0 box length represent extremes (arrow heads). The respective p-values are shown on the top right hand side of the graphs (multivariate ANOVA)
