I am replicating a two-way repeated measures ANOVA in a journal for practice. There are:
- One dependent variable
density
(I chose one from multiple dv presented in journal) - Fixed factor of drought (wet/dry year)
Years
- Fixed factor of grazing (no/light/moderate intensity)
Land_use
The data is collected from 10 plots for each grazing treatment for three months in each of the two years (wet/dry). The paper considered monthly observations as replications (thus 30 replicates per treatment), and integrated month as random factor.
Question: Is this a repeated measure because the drought factor was examined in the same plots (experience wet (2012) and then dry (2013))? Or is it because the dependent variable was measured in the same plot for three months (Jul-Sep for each grazing&drought pair)?
I don't think the latter is correct since month is considered as replications. But I saw from many websites that in repeated measures we compare more than two timepoints or conditions, whereas I only have two drought conditions.
Could someone clarify please? I am struggling ...
