I am running SPSS 24 on a Windows operating system. I am wondering how to run a nested ANOVA test on SPSS. I have two fixed variables and one random variables and cannot seem to work out how to handle more then one level of hierarchy.
The data set that I am working with is iron(II) concentrations in saltmarsh sediments. I have data from two different field sites (fixed variable or "the condition" as I have also seen it called) where 7 different depth increments were sampled. However, I did this depth sampling three times to assess soil heterogeneity. From what I understand, my field sites (field site 1 and field site 2) and the depth value that I made the measurement would be fixed variables, but the triplicate measurements would be random variables.
