Advanced Research Methods Quiz 2
For each, address: 1. Which design is it? 2. Pick one (or some) of the most relevant confounds for this project and discuss them. 3. Suggest an improved design. 1. Roger Research is interested in how people do with more sleep before a test. He measures performance on the first exam in a class, instructs the class on sleep before the second exam and has them get at least 8 hours the night before, then measures performance on the second exam.
For each, address: 1. Which design is it? 2. Pick one (or some) of the most relevant confounds for this project and discuss them. 3. Suggest an improved design. 2. Ella Experimenter wants to know if children who are read to more develop larger vocabularies. She randomly assigns children to four groups. She measures two groups of children s vocabularies and reads an hour a night for a month to one of these groups. She then measures both groups vocabularies. She has two more groups, one of whom she reads to an hour a night for a month and one of whom she doesn t. She also measures these children s vocabularies at the end.
For each, address: 1. Which design is it? 2. Pick one (or some) of the most relevant confounds for this project and discuss them. 3. Suggest an improved design. 3. Saul Scientist wants to know if a new drug is effective for ADHD. He has a group of children with ADHD not take the drug for a week, measures teacher-reported behavior problems, has them take it for a week, measures, has them stop taking it for a week, measures, and has them take it for a week and measures.
For each, address: 1. Which design is it? 2. Pick one (or some) of the most relevant confounds for this project and discuss them. 3. Suggest an improved design. 4. Isabelle Investigator is looking at the effect of diet on affect. She randomly assigns one group to eat her special anti-depression diet and leaves another randomly assigned group alone. She then measures both groups for depression.
For each, address: 1. Which design is it? 2. Pick one (or some) of the most relevant confounds for this project and discuss them. 3. Suggest an improved design. 5. Sammy Snooper wanted to know if visualization would improve free throw shooting. He measured a team s free throw shooting for four games, had them learn to visualize, and measured four more games.
