Unsure about best stats analysis to use



Hi all,

I am trying to figure out the best way to analyse a dataset. I realise this should have been considered at the beginning of the research. I am not confident enough yet with stats to just know by looking at it.

I am looking at the impacts of garden symphylan (GS) on 4 different crops with and without chemical inputs. Each crop was in a separate field. GS were counted on the different crops when they had no chemical inputs and then when the crops did have inputs.

I'm not familiar with what is best to use anova/ancova/t-tests etc. Based on this information above, what do you suggest?

I want to know if there is a difference generally between no input and input, and also any differences if the differences are crop dependant.

Thanks all
