How to run stats on C:N ratios

Question

Hi everyone,

In my research I am examining Carbon:Nitrogen ratios. I have been unable to figure out how to run a statistical analysis on these ratios, and maybe it is not possible, I do not know. Attached is my data. Any guidance on this would be appreciated.

Thank you

Whatever analysis you have in mind, I would suggest starting with some 'simple' graphs (reading the appropriate documentation if you need to). As an example (not a recommendation):

Since you know what the variables actually mean and what questions you want to address, you should soon be able to find a useful way to look at the data.

I change the ratio column to numeric values use the formula below, then you can run statistical analysis on this transformed column.

Num(Left(:Ratio, 2))

on the numeric vales.
