Hi Renier,
The Org-mode table machinery is interpreting the values of your table
cells as emacs lisp (given that the table formula is an elisp, rather
than a calc formula). Due to the "," the result is a weird nested list
which confuses your python code block. Some options here include...
1. wrapping these cells in quotes so that they are passed to the python
block as strings...
#+source: parameter-variation(data=0)
#+begin_src python :result values
return 'text'
#+end_src
|---------------------------------------|
| "(0.0331901438056,0.000535222885197)" |
| "(0.0333434157791,0.000537930174356)" |

| "(0.0357806926897,0.000575051685084)" |
|---------------------------------------|
| text |
#+TBLFM: @8$1='(sbe parameter-variation (nums @1$1..@7$1))
2. referencing the table from an external code block, rather than inside
of a table formula. This is probably the easier solution, but it
doesn't insert the result into your table, unless you do something
tricky like give the code block and the table the same name so that
the results of the code block replace the table...
#+results: complex-data
|-------------------------------------|
| (0.0331901438056,0.000535222885197) |
| (0.0333434157791,0.000537930174356) |
| (0.0345727512157,0.000559346040457) |
| (0.0353146483908,0.000571501584524) |
| (0.0355522909393,0.000574387067408) |
| (0.0356575682336,0.000574851263615) |
| (0.0357806926897,0.000575051685084) |
#+TBLFM: @8$1='(sbe parameter-variation (nums @1$1..@7$1))
#+begin_src python :var data=complex-data
return data
#+end_src
Hope this helps -- Eric
