This is what I will call a "qualitative graph". The question is: What is P? I can think of two particular answers, which together suggest an interesting analogy.

What do you think?

What is the Y axis?

P = time progression ?

The y-axis is purposefully unlabeled because it shows a quality rather than a quantity. We can say it is spatial distance, but then I want it to be interpreted like the y-axis in this image, which would be pointless to label.

P could represent power, in that a comparatively higher number of people congregate around centers of power and compete for positions of power.

P = number of consecutive free-throws a kid makes as he progresses at basketball.




EDIT
'qualitative' suggests there is no objective answer, only interpretations.

My two answer propositions:

P1= the amount of fear
P2= the "interestingness" of a conversation

P1= entropy, where the dots equal empty space

P2= alcoholism, where the dots equal drinks

P3= anger


I sure see a pattern!

Here, let me take a wild stab at it:

Taking aggregation for it's original Latin meaning, "Aggregation comes from the Latin ad, meaning 'to', and gregare, meaning 'herd'. So the word was first used to literally mean to herd or to flock."

P = time

Y axis = the concentration/population/"hang out locations" of sheep which steadily increases (or decreases) over time because, you know, animals like to mate, congregate, and die for extremely variable reasons.

So, clearly, this was a graph that a shepherd made in his spare time to roughly record the activity/population of his sheep. Kind of careless of him not to include the Y axis (or any clear, definable labels for that matter) though...





Edit: I should probably add that I've never been amazing with graphs...hehehe

I'm an idiot, but I'll try.

P1= Mitosis
P2= population increase in the world

Whoops, I thought that the P had to represent something that started with a P!

I suppose if P can truly represent anything, then the graph demonstrates a relationship of any thing to P, with the thing becoming more numerous and clustered as P increases.

Therefore, we could impose any positive linear relationship involving some kind of small groups or clustering on the part of the dependent variable. Another example that comes to mind is increased urbanization with either an increasing population or simply time progression (more P words but still).

I have a riddle too:
guess which one!



BTW, P is the degree of aggregation

It's fun to read everyone's answers

My two were animal Population density and Pressure. Social interaction is impossible unless population density is above some threshold, and a gas can be deposited in crystal form if pressure is increased sufficiently.

But the graph is labelled "aggregation versus P"... huh?







I was thinking P = pills...

Damn you

hmmm, it is still possible:
when P is the unit in which aggregation is represented as a measure like a mathematical instrument for statistics, then the aggregation is like how it looks like in real. P is then a calculable derivative of the phenomena aggregation and the *versus* is how these two relate to each other.
Voila

I would say p = Time & Space
Or p= Action & Reaction

But maaaaybe p= Frustration caused by you not giving us the answer
And the dots are our answers!

Yes! "Connecting the dots" to find the answer seems a logic thing to do

The amount of beers it takes before someone needs to P
