Was about to concede the point, but being the good science penguin that I am, rather than just eyeballing the graph and going "yeah theres some warming going on thar", I ran Pearson's correlation:
N: 180 (months)
r = .133
significance = .075
P > .05
Therefore not significant
:3
So yes, quite happy Trend-line schmend-schmine
I'm an SPSS newb though, so chances are I've done something horribly wrong (P < .05).
Oh man I cannot get away from this software lol. I am learning foundation of statistics as a prereq for my uni degree I want to get.
Looks like you have interperated the result ok, not sure about the data used though.
