Q1) Angeline is conducting an observational study of aggression on the playground. She is especially interested in whether boys are reprimanded more than girls for aggressive actions. The best instrument for her to use to collect her data would be:

1. A checklist
2. A rating scale
3. A rubric
4. A survey

Q2. Geoffrey is conducting a descriptive study focused on women’s rights. As part of his project, he reviews articles published in U.S. newspapers between 1850 and 1940. The best instrument for him to use would be:

1. A checklist
2. A rating scale
3. A rubric
4. A survey

 

Q3. Polly Petunia is Chief Horticulturalist for the Southwest region, encompassing Arizona, New Mexico, and Texas. She wants to survey amateur gardeners in her region to determine what, if any, water conservation practices they employ in their home gardening. Polly sends her survey to 150 randomly selected gardeners in each state.

Polly is using:

1. purposive sampling.
2. proportional stratified sampling.
3. systematic sampling.
4. stratified random sampling.

Q4. Paul Pollster, a political psychologist, wants to determine whether rates of voter participation in his home state vary between rural, urban, and suburban voters. He notes that there are more rural voters than suburban or urban voters in the state. Paul should use    in this study.

1. simple random sampling
2. cluster sampling
3. proportional stratified sampling
4. systematic sampling

Q5. Simon Cinema wants to know what the audience thought of tonight’s advanced screening of a heralded psychological thriller called “I Can’t Sleep.” He and his research assistants stand outside the theatre exit and ask every fifth person leaving the theatre to answer several questions about their impression of the movie. Simon is using:

 

1. systematic sampling.
2. stratified random sampling.
3. convenience sampling.
4. purposive sampling.

Q6. Jack Drive wants to know the relationship between intrinsic motivation and course grade among math students. He contacts a local professor who teaches several general education math classes and asks about the possibility of gathering data in her classes.

Jack is using:

1. simple random sampling.
2. cluster sampling.
3. convenience sampling.
4. systematic sampling

Q7. Edward Ethics is studying public opinion regarding prayer in public schools. He plans to gather survey data from a number of churches on Sunday mornings. He also wants to include a number of people who are not associated with an organized religion in his sample. Edward is using:

1. stratified random sampling.
2. cluster sampling.
3. convenience sampling.
4. purposive sampling.

 

Q8. Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to

1. response bias.
2. instrumentation bias.
3. researcher bias.
4. sampling bias.

 

Q9. Jody is interested in studying home schooling because she thinks that students who are home-schooled can’t develop appropriate social skills. As part of her study she will be observing home-schooled children in social settings. Jody’s planned study is particularly susceptible to

1. response bias.
2. researcher bias.
3. sampling bias.
4. instrumentation bias.

 

Q10. Rori is observing elite marching bands as part of her dissertation study. She is particularly interested in drum major leadership styles and behavior. She has found that the drum major at her current research site is very interested in showing off for her. This is an example of

1. response bias.
2. researcher bias.
3. sampling bias.
4. instrumentation bias.

 

Q11 PJ conducts an experimental study on the effects of soft music during high stakes science testing. He randomly assigns students at the school. In one condition he does not provide music for testing while in the other group he does provide the music. He administers a pretest at the beginning of the year and a posttest at the end of the year.

PJ’s design is best described as a:

1. Static group comparison
2. Pretest-posttest control group design
3. Control-group-time-series design
4. Nonrandomized control-group pretest-posttest design

Q12 As a secondary mathematics teacher, Hernandez conducted a study that explored whether giving children recess prior to testing helped their test performance. For one of the semesters, he sends half of his classes out for 10 minutes of recess prior to testing for the other half, he provides 10 minutes of free time after the test. Which of the following best represents the design of Hernandez’s study?

1. Static-group comparison
2. Post-test only control group
3. Solomon four group
4. One-shot case study

Q13. Kathy trains nurses. She designed a new assertive communication unit to include in her training. She administers a pretest and then randomly assigns nurses to her streatment or a control condition. She tests their communication skills before and after the treatment. She sees no significant differences at immediate testing but after eight weeks she retests the nurses and finds significant differences between her treatment and control students.    Which of the following best represents the design of Kathy’s study?

1. Non-equivalent groups
2. Solomon four group
3. Pretest-posttest control group
4. Post-test only control group

Q14 The primary difference between the Solomon four-group design and the two-factor experimental design is that ONLY the two-factor experimental design:

 

1. involves four groups of participants.
2. requires random assignment of participants to groups.
3. has a measurement before initial treatment.
4. includes two different treatments.
