Dear Christian, I am very glad you are explaining how to explore and test a
hypothesis. I am afraid that many of our members might not quite grasp
some things, so keep it simple. I feel I am learning much more about a weed
than I really care to. Could make a decent subject for A MS Degree research
project in agriculture.
How do you know? How many here do you know? If the present discussion affects your sensibility, there are hundreds of pages in the PBS wiki to read and see, in fact more than one could in months.
