Hi Martin,

» Would you also use mean (SD), rather than median (min, max), for the descriptive stats then, given that this then becomes a continuous variable?

Yes. The jury is out for years trying to figure out whether the distribution is normal (use \(\small{\bar{x},\,s_x}\)) or lognormal (use \(\small{\bar{x}_\textrm{geo},\,CV_\textrm{geo}}\)). See this thread for the Half-Value-Duration HVD (aka Peak-Occupancy Time 50) and the Plateau-time t75% (aka Peak-Occupancy Time 25). Like in you case both are also continuous in the time-domain.

Answering an unasked question: For discrete variables (e.g., tmax) I would give the median / IQR – not the range. The latter is not informative.

We absolutely must leave room for doubt
or there is no progress and no learning.
There is no learning without having to pose a question.
And a question requires doubt.
People search for certainty.
But there is no certainty.    Richard Feynman
