BUSN 5350 Research Methods Exam
Please fully answer each of the following questions. Remember that this is a graduate-level exam, so be sure to discuss each question in detail, using complete sentences and avoiding the use of bullet lists. Every question is a discussion, regardless of how it is worded so a list will not be sufficient to demonstrate that you have mastered the concept. This is an individual assignment, so any evidence of group work (including the use of internet sources/tutors) will result in failure of the exam, and potentially failure of the course for an honor’s violation. Please submit your responses, in order, in the following format: typed, double-spaced, in a 12-point font, with a header that includes your name and the page number.
- What is good research? Discuss this along with the 5 stages of research. What needs to happen at each stage?
- What are the three types of relationships between variables than can occur when testing causal hypotheses? Explain.
- Explain the three types of non-probability sampling techniques commonly used to select samples for research studies. Discuss the type(s) of sampling you’ll use in your project.
- What are the strengths and weaknesses of observational research? What steps might be taken to ensure the validity of this type of research?
- Discuss seven possible threats to internal validity. How do these threats weaken a design? How might these threats be dealt with?
- Discuss the three survey methods, including the advantages and disadvantages of each. Give examples of when/where each type might be most effective.
- Describe the four sources of error in measurement, including the possible causes of errors, and provide an example for each.
- Discuss the characteristics of a good measurement. Discuss how you will ensure that your survey instrument will display these characteristics.
- There are several possible issues that may affect measurement questions. Discuss the possible effects of question content, question wording, and response strategy choice on the quality of resulting data.
- Explain the researcher’s dilemma in deciding whether to use forced-choice rating scales or unforced-choice rating scales? What types of tactics can researchers use to minimize participant tendencies to avoid extreme judgments or choose extreme positions on a scale?
- What are the three types of questions that can be used when multiple responses to a single question are desired from the respondent? Explain each type of question and cite examples.
- What are the steps in drafting and refining a survey instrument, especially the phase of organizing the pieces? Explain the meaning of pretesting and why instrument designers should pretest questionnaires prior to using them in a study. Use your pilot study to illustrate the lessons learned.
- Data cannot be examined until it is entered and edited. What are the issues that must be considered when entering and editing data, with particular emphasis on coding?
- Discuss each step in the six-step procedure for testing for statistical significance. Why is it important for research to adhere to this sequence?
- Discuss the purpose of calculating measures of association. Pick any 5 measures of association and discuss the purpose of the analysis, the type of data used, and how the results are interpreted.
- “Research is worthless if you can’t communicate your results in a way that others can understand them.” Discuss why this statement might be true or false. How might data be displayed to better communicate results?
