The dependent variable is how well the students perform on the math test administered after one month 19.

There isnt really a placebo group, no one is receiving a fake treatment, they are either listening to music or not. 22. MrRoss randomly assigned students to the group that they are in to attend to prevent confounds. He also administered the same math test to both groups of students. 23. Experimenter bias is possible because Mr Ross could have graded the math test differently based on what group the student was. Also he could have interpreted the difference between the two groups as a result of the music barely it really was Just random chance. 24. The hypothesis is that Hawthorne believes that employees working in brighter light environments will have change magnitude productivity. 25.The independent variable is he setting in which the employees work, whether it is bright or dark environments. 26.
