Hi Helmut,

❝ ❝ Range: no expectation described. No idea.


❝ The range is completely useless. Like the mean it has a breakdown point of zero. Imagine with \(\small{n\rightarrow \infty}\): $$\small{\left\{R_1=1,\ldots, R_n=1\phantom{.25}\right\} \rightarrow \textrm{Range}(R)=0\phantom{.25}}\\\small{\left\{T_1=1,\ldots, T_n=1.25\right\} \rightarrow \textrm{Range}(T)=0.25}$$ Good luck in calculating a ratio.


I guess it depends what they mean by "range". Are they using the word in its statistical meaning (difference between the largest and smallest values) or in its lay language meaning (limits between which something varies) ? I suspect the latter: lowest and highest observed Tmax values.

Regards
Ohlbe
