Dear dr. Maris,

Bovenkant formulier
Onderkant formulier
I notice that there are many different views among scientists about the
use of one or two sided tests.
Most people say that you always have to test 2-sided. But is there a
rationale for this? When is it appropriate and allowed to test
Perhaps you can shed light on this topic, by giving your point of view
or perhaps you can recommend literature that provides insight on this

Thank you,
Best Emanuel
