Module 1 Activity 1

Part A.
#1-D Survey. Ahmed is asking many people a series of questions to gather information on their thoughts on the videos. Therefore it is a survey.

#2-C Laboratory Observation. Nadine is observing her test subjects in an unnatural environment. She is in a laboratory and is observing her test subjects.

#3- Survey. Ada is asking a number of questions to college student to gather information about their alcohol consumption.

#4- Psychological Tests. The document is observing or assessing Phineas Gage’s cognitive and behavioral abilities. This is the purpose of psychological tests.

#5- Laboratory Observation. Jerry is observing Ben Jones verbal and non-verbal behaviors in an unnatural environment of psychiatric hospital.

#6- Case Study. Dee is conducting an analysis on how the babies are reacting to the color of their bottle over time. Dee recorded the preferences after a year, which makes a it a case study. There is no control group so it’s not an experiment.

#9-F Experiment. It is an experiment because the doctor had a procedure done to a control group and an experimental group to be able to determine the result of the medication on the patients. The control group provides a base-line to compare the experimental group to.

Part B.
10-11. There is a positive correlation between taking the herbal supplement and receiving higher grades in the course.
Students who are more open minded to new things like herbal supplements are more open to different types of studying habits and perform well in the class.
Intelligent students realize the nutritional benefit of herbal supplements.

12-13. There is a positive correlation between preference for jazz music and high levels of sexual activity.
A preference for jazz leads to hanging at jazz clubs where active sexual activity is common among members.
People who are care free and free-flowing prefer jazz and are open to different sexual activities.

14-15. 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 incentivize their parents to keep them in pre-school longer.
Part C.
16. The hypothesis is that students will understand math material better when they study while listening to classical music.
17. 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 one 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 the 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.
