So would I. I would also fire a consultant who represented incomplete data as being complete. I want to see the assumptions, say:
"We took your customer database as of 2006-04-01 and analysed it by age as requested. Of the 1000 rows, one did not have age data, so we discarded it from consideration." etc.
If the analysis had non-age-related parts, then would that row be considered? Again, I would read the assumptions.
