Interesting. Maybe someone can post a venn diagram of which social
groups people in the ng are suspected of being in.
(and then everyone can beware the knock on the door!)


What is a venn diagram?

Yes, and we were getting along so well in English too.

Good to see you back after your absence Baz.

To clear up all the confusion, I offer the following copy and paste
from Wikipedia:

"Venn diagrams or set diagrams are diagrams that show all
hypothetically possible logical relations between a finite collection
of sets (aggregation of things). Venn diagrams were conceived around
1880 by John Venn. They are used to teach elementary set theory, as
well as illustrate simple set relationships in probability, logic,
statistics, linguistics and computer science (see logical
connectives)."

I think that explains things perfectly and simply and should serve to
end all further argument.

(I think Vicky was being tongue in cheek when she posted).

I will now wait for someone to explain the explanation to me (and no
doubt someone else will be able to explain the explanation of the
explanation).

Meanwhile, I'm going off-toipic to calculate how many shopping days
are left until Christmas.

Cheers

Jake

Ha, ha, very ironic! The first sentence is complete crap. They
show the 'inclusion' type relationships only.

It's a bad description, anyway. They are the overlapping circles
(or other shapes) that are often used to illustrate set membership.
The area in circle A but not in B represents the elements that
have propert A but not property B, and the area in the overlap
represents the ones that have both properties. And so on.

Nick Maclaren.

Laughing continues. Now I await someone who will explain the
explanation! This could really get interesting (though totally
off-topic; the definition of "on-topic" being the bit in the middle
which indicates the overlap between A, B and (of course) C).

Though I do wonder what the diagram would do if we introduced a
property "D". No need to answer that question - it's rhetorical
(assuming that's the word I'm thinking of). Work that one out ;-))

A bit like a Vector, a mathematical model to prove or disprove a theory?

Yes and no. They are used to demonstrate properties, rather than
prove them. They are more like graphs (in the school sense).

In more practical terms, I think they're used to demonstrate demographics,
etc, for advertising + management types

LOL, Nick, nice one.
It is surely a LOOONG time since you got your "degree in mathematics"

You obviously did your dissertation on the subject of how to be a knowall
and yet know very little (in the school sense).

I think you mean arithmetic.

It's one of those diagrams that looks like someone has put a bunch of coffee
mugs down on a sheet of paper, and all the people go in the circles. So the
coffee stain is 'people who are posh' and the tea stain is 'people who own
chickens' and the bit where the tea and coffee stains overlap is the posh
people who own chickens. And people outside both drink stains are people
who aren't posh and don't have chickens.
Then you can put a beer bottle down to make another circle that is 'people
who microwave their pork pies' and it can overlap the other 2 circles, and
you need to move all the people to their correct position again.

It's the sort of thing you do at school cos it's sort of fun, but if you
need to use it outside of school you're probably in the wrong job!

Cheeky! ;-)) I'm in at least 4 circles already - does Dante know about this?

That was infernally witty.

WIWAL, we called them "Euler circles", which makes me the oldest in
the thread so far.

I can never resist the temptation to try to explain maths!

Draw a circle to represent spring flowers (snowdrops, daffodils, winter flowering cherry, violets etc). Draw another circle, overlapping the first, to represent bulbs. The area which is inside both circles will contain this like snowdrops and daffodils - spring flowering bulbs. The rest of the second circle will have bulbs like leucojum which don't flower in the spring. The rest of the first circle will have violets and other spring flowers which aren't bulbs. The outside will have flowers which are neither spring flowering nor bulbs.

Or you could draw two circles, one inside the other, to represent "All cacti are succulents, but not all succulents are cacti".

They're useful to help visualise more complicated relationships than I've described, and usually with more than two circles needed. They were university stuff wen I was taught maths, but my children did them in primary school.
