Fluorescence scoring was quantified using Fiji. Scaling choices will impact how the data is presented visually on the plot, but will not affect the statistical value. While the Mean might be most useful when used to describe normal distributions and not bi-modal or multi-modal data, the Median is a non-parametric statistic in that it is a better indicator of the central tendency of your data, regardless of the underlying data distribution.
