Correlation 6
Dr. Farah : Correlation 4 is an example of which of the following types of correlations?

Which of the following studies is an example of a longitudinal design?
Dr. Benson's study in which she measured people's spatial manipulation ability in August and measured their ability again in May after they had taken two semesters of art classes
A colleague of Dr. Farah's questions the internal validity of her causal claim. He is curious as to whether the relationship between homework and academic achievement could be explained by interest in one's classes. Specifically, he thinks that students who are interested in their classes will both do more homework and have higher GPAs. Which of the following is a solution to this possible threat to internal validity?
Dr. Farah should also measure students' interest in their class.

Principle of beneficence
Dr. Kushner suspects that the people who will most benefit from his study are high school and college students, who are asked to perform cognitive functions in various states of sleep deprivation. Given this information, what type of participants should Dr. Kushner recruit for his study?
Students from a community college

If Dr. Finkel conducts his study again and asks people to report on how many years they have been married as well, which of the following statements is true?
The beta value for number of arguments may no longer be statistically significant.

Why would a researcher interested in making a causal claim NOT do an experiment?
There may be ethical limitations of manipulating a variable.

There were no ethical guidelines 5 years ago, but there are now.
