What does this mean

[Sancho]

I have been having hours of fun with this graph on Facebook. What does it tell us? Discuss...

It tells me that the value of organic food sold between 1998 and 2008 quadrupled.
It tells me that the number of individuals diagnosed with autism increased by a factor of 40 in the same period.

It doesnt tell me that there is a relationship.
It doesnt tell me if the volume/weight of organic food sold increased/decreased/ remained the same. ( for all I know an organic carrot could have increased in price, tenfold in that period )

Really it tells me not much . What is supposed to be telling me ?

Indeed, and you should be spending that time servicing and modding your motors
