When I was a student, most good statistics books included among all the other useful tables, a page of random numbers to help you meet a state of true randomness. I am ashamed to say that I think that very few of our own students would be able to cope with a week of teaching in French! There has been, and continues to be, much debate about what the catch actually represents. I found this very hard to believe so resorted to Twitter.
I leave you with two fun facts; the two largest motorised insect suction samplers that I have come across are both from the USA where else?

Then it was back to lecture to a fourth year group about biological control and pest management, again to a very interactive group of students.
A great post about sfary anyone from any background should be able to study and work in science.

I was convinced that this mode of sampling, which is more accurately described as haphazard, was commonly called professorial random sampling.

It seemed to go well and despite me lecturing in English they asked a lot of pertinent questions.
