It's titanic, as complicated for data analyst (12)
I believe the answer is:
statistician
'data analyst' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'it's titanic as complicated' is the wordplay.
'complicated' indicates an anagram (a complex or confusing ordering of the letters).
'its'+'titanic'+'as'='itstitanicas'
'itstitanicas' with letters rearranged gives 'STATISTICIAN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for statistician that I've seen before include "Analyser of figures" , "One analysing data" , "Expert in numerical facts" , "One analysing numerical facts" , "Numerical data analyst" .)
