So cosy

The eye is extremely sensitive in green, so you can have different shades of green... Though, you might want to try dual encoding e.g. shape too, as red-green colour deficiency is the most common. cusplondon.ac.uk/vizent/gallery

If you have no hypothesis you are doing no better than random guesswork. Not sure it is even ethical to collect the data.

If that is their point then I agree, just showing a mean gives no information about the distribution... But we don't need a study to tell us that.

The more I read the worse it gets, two of three fallacies they claim, could in fact easily be real data. Their assertation that the normal range in green is an accurate gold standard, is meaningless, we have no idea what the real data is from just the mean in the bar charts.

hmmm, not a good experiment- give people a mean and ask them to guess the distribution - it is not surprising they can't do it - they are asked to guess Anscombe's quartet from the mean. it is almost a deception experiment - since there are an infinite number of possible answers and no right answer

What value do the heights represent? They seem to be straying from axes conventions.
