Environmental stats



First of all, I am pretty useless at statistics hence why I have come here for some help.

Essentially I have data relating to sediment stability (dependent variable) and fluorescence, water content, total carbohydrate, colloidal carbohydrate, and grain size (all independent variables)

All variables were recorded over a two day period at sites containing algal growth and sites without algal growth (evenly distributed)

Essentially I would like to find out if the sediment stability is affected by the independent variables, and if there is any difference between the day 1 data and day 2 data. Could you please explain how I would go about this, I have been suggested a one-way anova. Also I have access to spss.

I hope I have explained well, if not then please ask for more details.
