Webbthree pit blinds were used as blocks in the experiment. Thus, a randomized block design with three treatments (decoy types) and three blocks (pit blinds) was employed. The response variable was the percentage of a goose flock to approach within 50 meters of the pit blind on a given day. The data are given in the following table. WebbThe term repeated measures is used when you give treatments repeatedly to each animal or participant. The term randomized block is used when you randomly assign treatments within each cluster (block) of matched subjects. Imagine that you compare three different treatments.
