2. Data
Florida Swamps Classified in 3 Size Categories: Small, Medium, Large (Fixed Factor)
3 Swamps sampled from each size type (Random Factor)
27 locations sampled and water levels measured, in cm.
Yijk represents the water level for the kth location of the jth swamp within the ith size level
Mean (SD) for the 27 locations for the 9 Swamps (Approximated from paper)
