1.2 Formulate (3) research questions that the proposed study will attempt to answer.
1.3 Select and discuss an appropriate research design for the proposed study.
1.4 Critically discuss the methodology of the proposed study with respect to the following:
1.4.1 Specify the target population for the proposed study and discuss whether your sample
1.4.2 Specify a method of sampling for the study and justify the appropriateness of this
1.4.3 Specify a suitable data collection method for the study and rationalise the selection of
1.4.4 Briefly discuss the methods of data analysis that you would use in your study
Question 2
Using your understanding of ethical principle in research, critically discuss each of the following dimensions of research ethics and specify how you would implement them in the proposed study.
2.1 Non-maleficence
2.2 Plagiarism
2.3 Social and cultural sensitivity
Question 3
Study the information provided below and answer the following questions.
As part of a preliminary investigation aimed at unpacking the relationship between CEO tenure and the financial performance of JSE-listed companies (i.e., the second research objective), you have gathered secondary data on average profit margins (a proxy for financial performance) during the tenure of 20 CEOs of JSE-listed companies
Required:
3.1 Based on the information provided above, specify the independent variable (IV) and the dependent variable (DV) as well as the level of measurement of the IV and DV.
3.2 Using your understanding of quantitative research, formulate the null and alternative hypotheses for the preliminary study described above.
3.3 From your observation of the output of the data analysis depicted in Figures 3.2 to 3.7, specify the purpose of the statistical tests conducted and evaluate the findings from Figures 3.2 to 3.7.
3.4 From your observation of the output of the data analysis depicted in Figures 3.8 to 3.13, provide a comprehensive interpretation of the findings of the preliminary study. Include the standard reporting format in your interpretation
Question 4
Study the information provided below and answer the following questions. To determine whether CEO tenure differs significantly across the different economic sectors in which JSElisted companies operate (the first research objective), you are comparing CEO tenure of JSE-listed companies operating in the financial, consumer goods and mining sectors. The data in Table 4.1 represents the preliminary data collected from 30 JSE-listed company.
Required:
4.1 Based on the information provided above, specify the independent variable (IV) and the dependent variable (DV) as well as the level of measurement of the IV and DV.
4.2 Using your understanding of quantitative research, formulate the null and alternative hypotheses for the investigation described above.
4.3 Suppose that the assumptions of parametric tests are met, specify and justify a statistical test that you would conduct to ascertain whether the CEO tenure of JSE-listed companies operating in the financial, consumer goods and mining sectors differs significantly.
4.4 Suppose that the assumptions of parametric tests are violated, specify and justify a statistical test that you would conduct to ascertain whether the CEO tenure of JSE-listed companies operating in the financial, consumer goods and mining sectors differs significantly.
Question 5
Research design reflects primarily the purpose of research; Therefore, before the design of a study can be developed, its purpose or purposes should be formulated. In the light of the above observation, compare and contrast exploration and explanation as distinct purposes of research design.
