Hi guys... Maybe these are obvious and I'm missing something but I couldn't really find an answer online so I was hoping someone can help me out with some general questions regarding correlation.
If given a statement of positive correlation such as "as A increases, B increases," how much can we validly infer?
Can we infer all of...
-as A dec B dec
-as B dec A dec
-as B inc A inc
Also for negative correlation -"as A increases, B decreases"
Can we infer all of...
-as A dec B inc
-as B inc A dec
-as B dec A inc
Thanks in advance :)
I think conventional wisdom is that don't take the test until you feel you are ready, since you only have 3 chances to take the test.
