Discussion:
Compare data from a study I have been doing, but don't know which statistical tests to use. I have surveyed 40 hedgerows:
20 from site 1
20 from site 2
Q1). Find out the significance of difference between the 2 sites in terms of their 'woody species' composition. Would something like a t-test work for this?
Q2). Do some stats on other attributes of the hedgerows.
