Penny Poodle wanted to know which dog obedience training program was more effective: Puppy Pride, the approach she has been usin

The dogs and their humans were randomly assigned to complete the Puppy Pride or Doggie Do-Right course. At the end of the training programs all of the dogs were scored on their level of obedience on a standardized dog obedience checklist (scores could range from 10 to 100). The study employed what type of design? a. One shot experimental b. Ex post facto c. Posttest only control group design d. Within subjects
Penny took untrained puppies and randomly assigned them to different groups without having a control group (of non-trained dogs). She also used a single measurement (the standardized dog obedient checklist) and used as a post test.
