I need to do statistical analysis for my A level biology coursework and i can not get to grips with it my coursework is to do with the effects of soil salination on the germination of wheat and barley seeds. Basicaly i germinated wheat and barley seeds in different concentrations of salt solution and measured the length of the radicle emerging from the seed
Here are the results:
Cocnetration of solution Length
I just want to know what statistical test i should use to analyise my results
If you are trying to link length of radicle to salt concentration, you will need Spearman's Rank Correlation test.
