There is a positive correlation between the longer a child attend pre-school and high IQ scores. Children who can afford to spend a lot of time in pre-school have parents who are wealthy and likely educated, providing them with good genes and thus are likely to have high IQ scores. Children with high IQ scores perform well in pre-school and incentives their parents to keep them in pre-school longer. Part C. 16. The hypothesis is that students will understand math material better when they duty while listening to classical music. 7. The independent variable is the setting in which the students study, whether that is with classical music or no classical music. 18. The dependent variable is how well the students perform on the math test administered after one month 19. The experimental group is the group of students who study math while listening to Mozart. 20. The control group is the group of students who study without listening to music. 21 . There isn't really a placebo group, no on e is receiving a fake treatment, they are either listening to music or not. 22. Mr†¦Ross randomly assigned students to the group that they are in to help 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 but it really was Just random chance. 24. The hypothesis is that Hawthorne believes that employees working in brighter light environments will have increased productivity. 25.The independent variable is he setting in which the employees work, whether it is bright or dark environments. 26. The dependent variable is the productivity of the workers. 27. The experimental group is the group of employees that work in the brighter work environment (100 watt lighting). 28. The control group is the group of employees that work in the regular lighting area (70 watt lighting). 29. There is no placebo because there is no fake treatment or pill that is given for psychological benefits of the patients, there are just 2 group, one with 100 watt lighting and one with 70 watt lighting.
