11.Dr. Marbles decides to adopt an unconventional (and rather inappropriate) way of assigning grades to students in his Introductory Psychology class. Three times throughout the semester, he has his students line up from tallest to shortest. He then assigns A’s to the fifth of the class that is shortest, B’s to the next fifth of shortest students, and so on (so that the fifth of the class that is tallest receives F’s). At the end of the semester, Dr. Marbles averages across these grades to determine a final grade. While Dr. Marbles’ grading methods may seem problematic, which of these statements is true about the students’ examgrades? 12.True/False: Random assignment is a critical component of correlational research. 13. Which statement addresses why random assignment of participants to conditions is necessary for an experiment?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
