I think that's a good enough reason to not include them in the stats, but I find the use of percentages confusing over simply the raw numbers?
20 People. 3 Not Looking, so removed. It mentions your fellow students, so minus 1 more and we're down to sample size of 16. 88% of 16 is 14.08 - 14.08 people is a weird number. Maybe the maths was done including yourself, so that'd be 17... which gives us 14.96 people - so that doesn't make sense either?!?
Surely something like "Out of his fellow students 16 were looking for, and have job offers on the table. 10 of whom are headed to startups, with the other 6 mostly employed at consultancies." My numbers aren't accurate, but I think the sentence is much clearer.
This is an aside though, congrats on being brave enough to go off to another country to do this - never an easy choice, though sometimes here on HN it comes across as not-a-big-deal.
I'm Lachy Groom, btw.
