Hi all,
I have a data set like this one.
What I would like to do is a significance test to see if the number of species in night period is significantly higher than in day period or vice versa
df <- tribble(
~period, ~Sp, ~value,
'day', 'Atlanticus', 2,
'day', 'Olrikii', 1,
'night', 'Medius', 5,
'day', 'Glacialis', 7,
'night', 'Unidentified', 3,
'day', 'Glacialis', 2,
'day', 'Medius', 4,
'night', 'Capilatta', 17,
'night', 'Olrikii', 1
)
what kind of test can I do and how can I do it ?
Thanks a lot
