choccake: Chocolate cake experiment with split plot design
Description
An experiment was conducted to determine the effect of recipe and
baking temperature on chocolate cake quality. 15 batches of cake
mix for each recipe were prepared. Each batch was sufficient for
six cakes. Each of the six cakes was baked at a different temperature
which was randomly assigned. Several measures of cake quality were
recorded of which breaking angle was just one.source
