Trend analysis of Rainfall
I has rainfall data for which I did linear trend analysis using parametric test for various seasons.
In one season for example, I got slope 6.1 mm/decade and p value 0.0001. while for the other seasons I got slope 4.5 mm/decade and p value=.90. slope indicate that both the data has the trend. One is statistically significant and other not.
My question is, why I am saying to one has trend and other has not? And when both has such high slope why one giving significance result and other not??
