Really not sure which, if any, to exclude from the range here. The highest value seems like an outlier, just because there are so many sales so much lower plus the c9 robo glove is outdated and there were not many sales available for a mini so might not be too accurate. Gonna cut that one and round the range 20-30. Any feedback is appreciated.
