For this data, I am looking at the relationship between bee population (1000s of bees) and area of genetically modified crops (km2).
I have generated a scatter graph using this data:
What is the most appropriate correlation method to use here?
In my opinion, there does not seem to be a monotonic relationship between the data. Therefore, is this data parametric, therefore follows a normal distribution? Therefore, out of three types of correlation (Pearson, Spearman, Kendall), is Pearson the most appropriate method to use for this data?
Maybe I am incorrect in my assumptions. Perhaps you can help?
