Well I suppose it depends what sort of statistical analysis you wish to use. But for comparisons of percentage cover of vegetation I have always used IBM SPSS, you can just load an XL spreadsheet into it, select your analysis and away you go!

If it’s just a one off thing then you can get a 14 day trial here: http://www14.software.ibm.com/download/data/web/en_US/trialprograms/W110742E06714B29.html

 

Hope that helps!

 

EDIT: If you are unsure on what analysis to use you can do some googling but I found how2stats' videos on youtube very helpful; maybe look at ANOVA's and t-tests to get a grip with it.

You want to use a test of proportions:

They're a very common need, so you can find them implemented in whatever statistical software you use. You can probably make an Excel formula to do it, even.

Tnx for all the reply It helps.
