Stats help for dissertation
My dissertation title is “what is the most significant factor in determining Jaguar (Panthera onca) density”
My Independent Variable is Jaguar density per 100km/2 (results from Argentina, Belize, Bolivia, Mexico and Peru)
Dependant variable 1 is Temperature (average for year)
DV 2 is Precipitation (average for year)
DV 3 is NDVI results for the country (for relevant years)
DV 4 is Forest Loss for individual years (extracted via Google Earth Engine- Hansen et al dataset)
The issues I have now is with Argentina. For the remainder of the results I gave statistically tested the DV’s with the IV using Spearmans rank correlation coefficient. However, the Argentina Density results for the Jaguar were 0 (I thought this would be good to show 1 country with no density results), I cannot seem to be able to run Spearman with 0 values on both excel or SPSS.
Is statistical analysis impossible because the IV is 0?
If so how should I present this in the results section? Graphical representations?
If anyone could give me a hand on this it would be muchly appreciated!
