Identify potential extraneous and confounding variables in the description below. Iris IUS noticed that some seats in one particular classroom were especially good, and others were especially bad. The bad seats had a poor view of the professor, a noisy (and oddly ineffective) heating duct overhead, and several support pillars further blocking the view. She suspected that these seats were giving an unfair disadvantage to those students who sat there, so she conducted a study to find out. She tracked people's seating patterns and identified 2 groups: a control group who sat in the good seats more than 80% of the time, and an experimental group who sat in the bad seats more than 80% of the time. At the end of the semester, she found that "good seat students" received significantly higher grades than those in the bad seats. Armed with these findings, she is currently organizing a sit-in at the Chancellor's office demanding that the seating be improved in this classroom. A.) Identify some potential extraneous variables in this study (2 to 3 is sufficient) B. ) What is her independent variable and what variable is most clearly confounded with it? C.) What could she do to most directly eliminate the confound in this study?
