- Delay: time (minutes) to get to work (could be empty)
- Nocturnal: 0 (work by day) 1 (work by night)

we want to know the relation between delay and nocturnal. So:

- How can we check the normality of the variable?
- How can we make a parametric test to contrast the existence of the relation (even if the test it is not appropiate)
- How could we make a non parametric test (even if it is not appropiate)

Could you help me? I'm newbie in this subject and feel lost about tests, how to choose the right ones, etc.

Thank you in advance.
