Hi, I posted recently on here for help with a small hobbyists beekeeping study and was met with great help from user Karabiner.
Because of this, I'm hoping that the community can offer some extra statistical advice that will also settle a disagreement between myself and my colleague.
In essence, we have a database going back seven years (2013 - 2019) consisting of records we've kept. In these records, we have the levels of parasites found (Varroa destructor) on the bees. This parasite is pretty common and is typically recorded as either low, medium or high (To use it in SPSS I converted it to 1=low, 2=medium, 3=high).
we hope to see if there were any "bumper" years of varroa might presence in our hives. My colleague thinks we should do a Pearsons correlation, but I was under the impression that Spearman's ranks was what you needed for ordinal data like low, medium and high?
Are either (or neither) of us correct?
Thank for any help!
