How do I have a boxplot for three or more dependent variables on one graph with the ANOVA significance letter? For example, I have the following data set:
:Treatment :Replication :Feed_intake :Body_weight Milk_yield Maize 1 23 233 22 Sorghum 1 32 231 23 Wheat 1 34 323 22 Maize 2 12 342 12 Sorghum 2 23 122 32 Wheat 2 14 323 23
So how I can have the three dependent variables (Feed_intake, Body_weight, and Milk_yield) boxplot with their ANOVA significance letter on one graph?
