Question 1: Three of the following are characteristics of a well-written research problem. Which one is NOT?

• The problem statement includes jargon associated with the field.
• The problem statement clearly delimits the object(s) of study.
• The problem statement identifies the important factors to be investigated in the study.
• The problem statement explicitly identifies assumptions.

Question 2: Three of the following comprise the setting of the research problem. Which one does NOT?

• A clear description of all measurement tools to be used in the research project
• A clear statement of what the researcher will and will not do in the course of the study
• A clear statement of the assumptions on which the research problem rests
• A clear definition of all terms related to the research problem that might be misunderstood by a reader

Question 3: Research problems, as defined in your textbook:

• are identified by experts in the field, and not typically knowable by novices
• clearly and completely specify important questions that are currently unanswered in a particular field of inquiry.
• are broad, general statements about the incomplete state of understanding in a particular field of inquiry.
• can be addressed by compiling and synthesizing existing information in a way that sheds light on the issue of interest.

Question 4: Basic research is:

• research intended to enhance basic knowledge about the physical, biological, psychological, or social world or to shed light on historical, cultural, or aesthetic phenomena
• large scale research performed under contract with a governmental agency such as the National Science Foundation (NSF), National Institute of Mental Health (NIMH), etc.
• informal research conducted locally by a small staff with a small budget, the purpose of which is to pave the way for larger research initiatives.
• research intended to address issues that have immediate relevance to current practices, procedures, and policies.

Question 5: A common weakness of research problems is that they:

• delimit the object(s) of study.
• constrain the variables to be investigated.
• implicitly rest on common assumptions.
• incorporate a number of subproblems.

Question 6: Which of the following represents a well-written applied research problem?

• "How does the organization of mathematical information in long-term memory differ between 3-year-olds and 13-year-olds?"
• "How do business teams of six or fewer members compare to teams of more than six members in terms of productivity?"
• "Which general education course is more interesting, Australian History or World Music?"
• "What is the ratio of native-born students to international students on the campuses of public Australian universities?"

Question 7: "What is the correlation between an index of civic-mindedness and years of involvement in local organizations and charities among members of city councils of selected midsized cities in Australia?"

The chief weakness of this research problem is that:

• it implies only description of the data, not interpretation.
• it does not lead to the creation/discovery of new information.
• it lacks clarity or completeness in the problem statement.
• studying the question as stated is not feasible.

Question 8: "What proportion of workers hired by selected mining companies in Queensland between 1995 and 2000 held three-year university degrees?"

The chief weakness of this research problem is that:

• it lacks clarity or completeness in the problem statement.
• it implies only description of the data, not interpretation.
• it does not lead to the creation/discovery of new information.
• studying the question as stated is not feasible.

Question 9: Which of the following represents a null hypothesis?

• Class A high school basketball teams who employ a sports psychologist will have a higher proportion of wins over the course of the season than comparable teams who do not employ a sports psychologist.
• There will be no difference in rate of skill improvement between college gymnasts who practice meditation and those who do not.
• Does incorporating relaxation exercises into the daily practice routine of college vocal majors enhance their performance confidence?
• None of the above

Question 10: Marcos s study suggested that elementary students who watch TV more than three hours a day are more likely to be overweight than students who watch less TV. In this study, students weight is

• An independent variable
• A dependent variable
• A mediating variable
• A moderating variable
