Nested Design:
Multi-way design:
Challenges:
To perform a two-way complete model ANOVA in R you would first import datafile "Trout3.txt", then you need to make sure that pond size and pond depth are treated as a categorical variables
This is equivalent to piecing the terms together from a series of one-way ANOVAs. First create the model for the consistent size effects using a one-way ANOVA on PondSize, then report the results
then you create the model for the consistent depth effects using a one-way ANOVA on PondDepth, then report the results
then you create the model for the one-way ANOVA on the specific combination of PondDepth and PondSize, then report the results
the SS and df for Model.4 minus those for Model.2 and Model.3 are associated with the interaction between depth and size |
