In these designs, you usually compare one group's outcomes before and after a treatment (instead of comparing outcomes between different groups). 4. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. You make an observation, have a question about your observation, form a hypothesis about how it works, test your hypothesis and then form new questions and hypotheses based on the results. Ethology is the study of animal behavior. Then she uses that information to form a tentative answer to her scientific question. different from pill bugs.
