Question 4: (12 points) Please read the following research designs and write down whether it is an experimental, quasi-experimental or qualitativeon-experimental design. Also write down which type of design is used (e.g., case study, post-test only, etc.). Motivate all of your answers! a. Veronique wants to investigate whether dogs behave less aggressive when they consume only natural products. She selects dogs through the dog training institute she works in. Half of the dogs who participate receive natural food products and half of the dogs receive food products similar to regular available dog food. Owners are not aware which kind of food their dogs receive and dogs are appointed arbitrarily to any type of food. Veronique observes the participating dogs behavior before and after they start consuming the food products she has given them. b. Kees is interested to know why people radicalize. He decides to follow a small group of people with similar worldviews and backgrounds and compares the circumstances and characteristics of people who have committed violence with those who have not. c. Casey wants to investigate how students' life satisfaction changes after graduating. She follows a group of students who fill out a survey on life satisfaction half a year and 1 month before they graduate, and 1 month and half a year after they graduate
