-Year (2001 and 2006)

-Transect (37 transects)

-Plot (50 points along transect where the nearest shrub measured, this was done for 3 shrub types so there is 3 species) Between the two years, they may not be the same plants nor the same species observed at each plot.

-Form class (the amount or severity that the shrub was eaten by deer and elk) This is in classes- 1-lightly browsed, 2-moderately browsed, and 3-severely browsed.

I want to test the significance of the increase or decreases of browsing. Lightly browsed shrubs decreased greatly and severely browsed increased greatly.

I am having trouble setting up a Chi-squared in systat and need some help.

I am assumming that the chi-squared in systat I want would be the 2 sample KS-test?

I have been bringing the data in, choosing data by groups, and using species as my grouping variable since I want to analyze each shrub species seperate.

I then go to 2 sample KS test,

Putting form class as my variable, year as my grouping variable.

But that seems to just analyze the difference of the numbers between the 2 years, not the classes themselves. I need to know whether there was a significant difference in the number of class 1's, class 2's, and class 3's.

Am I grouping something wrong??

Thank you so much for the help.
