A solution could be to get rid of these strange values. Using the standards approach of removing everything below and above a value based on 1.5 times the interquartile distance, we can redo the above graphs.

The Cullen and Frey graph then transforms to:

The distribution is now very close to what we expect for a Gaussian distribution (the star). Looking at the density plot:

The density plot seems to suggest that there are two Gaussian distributions, which might explain the offset in the Cullen and Frey plot.

The QQ-plot now behaves much better:

Note that the sample quantiles seem very similar at -1. I suspect that these are theoretical values taken from Ciqual or similar. Could this be an explanation for the second peak? The Ciqual value is 52.5
