Q1) Define the focus of the observation study in quantitative research.

Q2. Of the following research topics, which is most likely to be an observational study?

 

1. The relationship between hours of exercise and sleep.
2. The difference in minutes a day exercising between boys and girls.

 

3. The types of exercise students engage in after school.
4. Students’ feelings about after-school track practice.

Q3. Correlational research allows the researcher to answer questions such as:

1. what is the relationship between Variable A and Variable B?
2. does change in Variable A cause change in Variable B?
3. is there a significant difference between scores on Variable A and scores on Variable B?
4. does change in Variable B causes change in Variable A?

Q4. Which of the following is an example of a good research question for a correlational study?

1. What are the attitudes of the parents about our districts new homework policy?
2. Is there a relationship between student achievement and homework completion?
3. Are there differences in parent attitudes about homework between mothers and fathers?
4. How much homework does the average fifth grade teacher in our district assign?

Q5. A researcher wishes to study developmental changes in people’s preference for action movies. The researcher locates 50 people at each of the following ages: 15, 20, 25, 30, 35, 40, 45, and 50 years. She asks them to rate their preference for action movies in relation to other sorts of movies. This is an example of which type of design?

1. longitudinal
2. nested
3. cross-sectional
4. panel

Q6. A researcher wishes to study developmental changes in the music people prefer to listen to. The researcher locates 50 people who are about 20 years old. She sends these people a questionnaire every year for the next 10 years asking about the types of music they prefer to listen to. This is an example of which type of design?

 

1. longitudinal
2. nested
3. cross-sectional
4. panel

 

Q7. Which of the following scenarios best illustrates a cohort-sequential design?

1.      Don studies high school students’ concerns about world events during their 9^th, 10^th, 11^th and 12^th grade. He surveys the entire 4 grades classes state-wide. He surveys them again every year for four years.
2.      Melanie is conducting a survey for her thesis that examines administrative policies in middle schools that are intended to decrease bullying. After developing her survey and piloting the instrument with a small group, she then administers the instrument to a sample of 2300 middle-school administrators.
3.      Jana wants to understand what predicts student success on the statewide standardized biology competency test. She administers the Biology Interest Survey (BIS) to all of her students at the start of the term and then categorizes students into two groups: those who have taken biology before and those who have not. She then administers an in-class exam at the end of the term.
4.      Molly’s study examines the benefits of exercise on weight loss. In one group she advocates exercise as well as a new diet program. In the comparison group she only presents the diet program. Those in the comparison group find out that some of Molly’s clients are in an exercise program too, so they form an exercise group on their own.

 

Q8. Among survey methods,            generally generate the highest response rate.

1. telephone interviews
2. interviews using video-conferencing
3. face-to-face interviews
4. online surveys

 

Q9. Advantages of questionnaires include all of the following EXCEPT:

1. large numbers of people can be contacted for a relatively low cost.
2. data can be gathered from a large number of people in a relatively short period of time.
3. participants may feel more confident about their anonymity and therefore respond more honestly.
4. because questions are in written form, they are less likely to be misunderstood by respondents.

 

Q10. Regarding the length of questionnaires to be used in survey research, which of the following statements is most accurate?

1.      Including a large number of items on the survey assures that you will get useful data for all of your trouble.
2. Keeping the survey short makes it more likely people will be willing to complete it.
3.      A relatively lengthy survey communicates your seriousness about the research endeavor so people will be more willing to complete it.
4. Shorter surveys produce data that are ambiguous and therefore not useful.
