Hmmm... If I copy and paste just
dist = WeibullDistribution[7, 200];
data = RandomVariate[dist, 300];
ProbabilityScalePlot[data, "Weibull"]
into a single cell then execute it, I see the error you
reported. Alternatively, if I type the above by hand into a
single cell I still see the error you reported consistently. Or
I can copy each line one by one pasting each into a cell then
execute each line before pasting the next and still get the error.
But if I enter each line by hand into individual cells, I don't
see the error. So, there appears to be a bug somewhere. That is,
the various ways I've described above of doing the computation
should all behave identically.
