RESEARCH STUDY 9.1: Dr. Farah is an educational psychologist who is interested in studying the potential causal relationship between doing homework and academic achievement. In January, Dr. Farah has her students report their fall GPA (a measure of academic achievement) and estimate how many hours they spent doing homework during a typical week in the fall semester. In May, Dr. Farah measures the same variables again (the estimated number of hours spent doing homework during a typical week in the spring semester and their spring GPA). She finds the following correlations:   Variable A Variable B Correlation Coefficient Correlation 1 Fall number of hours of homework Fall semester GPA .83* Correlation 2 Fall number of hours of homework Spring number of hours of homework .36* Correlation 3 Fall number of hours of homework Spring semester GPA .69* Correlation 4 Fall semester GPA Spring number of hours of homework .18 Correlation 5 Fall semester GPA Spring semester GPA .45* Correlation 6 Spring number of hours of homework Spring semester GPA .80* *Indicates a statistically significant relationship.   Based on her pattern of correlations, which of the following can Dr. Farah safely conclude?

RESEARCH STUDY 5.1: Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Donal scale. Question 1 reads, “I tend not to think about other people as much as I think about myself.” Question 2 reads, “I do not have a high opinion of myself.” Question 3 reads, “I think other people think I am really special.” Before using the measure in her study, Dr. Rodriquez analyzes the data she gets from her students. She looks at the relationship between each of the individual questions. She sees that participants who agree with Question 1 also agree with Question 3 and disagree with Question 2. This is a test of which of the following?

Anderson is reading his morning paper and sees the following headline: “Men Should Avoid Rock Music When Playing Board Games.” (This headline is based on a study conducted by Fancourt, Burton, & Williamon, 2016.) In the study, men and women played the game “Operation” when listening to different types of music. Male participants performed worse when listening to AC/DC than when listening to Mozart, but female participants’ performance did not differ based on music. In this study, the researchers recorded how many errors participants committed. This is an example of which of the following?
