Project #38099 - Research Methods

 

Complete the even-numbered problems for the designated chapter(s) in the textbook. Students are highly encouraged to complete all problems in each chapter, as odd-numbered problems increase understanding of even-numbered problems (answers to odd numbered problems are located in appendix A at the back of the text.

 

1. Chapter 3, module 5, exercise 2

 

2. Chapter 3, module 6, exercise 2

 

 

 

(2). Identify the type of measure used in each of the following situations:

 

 

 

a. As you leave a restaurant, you are asked to answer a few questions regarding what you thought about the service.

 

 

 

b. When you join a weight loss group, they ask that you keep a food journal noting everything that you eat each day.

 

 

 

c. As part of a research study you are asked to complete a 30-item anxiety inventory.

e. While eating in the dining hall one day, you notice that food services have people tallying the number of patrons selecting each entrée.

(2). When you arrive for your psychology exam, you are flabbergasted to find that all of the

 

questions are on calculus and not psychology. The next day in class, students complain so much that the professor agrees to give you all a makeup exam the following day. When you arrive at class the next day, you find that, although the questions are different, they are once again on calculus. In this example there should be high reliability of what type? What type(s) of validity is the test lacking? Explain your answers.

MODULE 1

 

 

 

 

 

2. Provide an argument for the idea that basic research is as important as applied research.

 

 

 

4. An infomercial asserts, A study proves that Fat-B-Gone works, and it will work for you also. What is wrong with this statement?

 

 

 

MODULE 2

 

 

 

(2). In a research project intended to gather data on the effects of type of study method on examination performance, participants are randomly assigned to one of two conditions. In one condition they study alone, using notes they took during class lectures. In a second condition participants study in interactive groups with notes from class lectures. The amount of time spent studying is held constant. All students then take the same exam. In this study:

 

a. What is the independent variable?

 

b. What is the dependent variable?

 

c. Identify the control and experimental groups.

 

d. Is the independent variable manipulated, or is it a participant variable?

 

 

 

(4). Gerontologists interested in the effects of age on reaction time have two groups of participants take a test in which they must indicate as quickly as possible whether a probe word is a member of a previous set of words. One group of participants is between the ages of 25 and 45, whereas the other group is between the ages of 55 and 75. The time it takes to make the response is measured. In this study:

 

a. What is the independent variable?

 

b. What is the dependent variable?

 

c. Identify the control and experimental groups.

 

d. Is the independent variable manipulated, or is it a participant variable?
