I posted a topic yesterday, and I assumed I had the issue "solved" so to speak. However, after much deliberation last night I think I may be back to square one, plus I have a few other queries I would would be ever so grateful for help with.

I want to establish whether covering affects the abundance of insects onto a corpse. I was using a Chi-Squared test, but as the majority of my data values were below five, it was decided that I would use Fisher's exact test. When I performed this test I came up with a p-value of 1.000, which would suggest that there was no affect by covering; but to look at the data it would be obvious that there is a difference in abundance.

An example of my data set is attached as an excel spreadsheet. I believe the issue to be the number of data points with zero. Essentially, I would like to know where to go with this data; i.e. what tests can I do?

I also have to investigate the correlation between temperature and rainfall on overall abundance; can I do both factors at the same time?

I also have access to Excel with XLStat and Minitab.

Sorry I had to post a separate thread, and thank you for any help; i'm a complete statistics novice.
