HMEMS80 SEMESTER 2- FEEDBACK FOR ASSIGNMENT 02 | Questions with correct answer (in bold), explanation and references 1. Which one of the following is a synonym for an independent variable? 1. Treatment variable. 2. Criterion variable. 3. Outcome variable. 4. Restricting variable. An independent variable is also referred to as either an input or treatment variable (depending on which reference you use). Please see Table 2.1 on page 24 of your textbook. 2. Your line manager asks you to start a research project to determine the relationship between employees’ intention to leave the organisation and their levels of work engagement. Which one of the following research decisions would be the most effective? 1. True-experimental. 2. Regression. 3. Quasi-experimental. 4. Correlational. As soon as we talk ‘relationships amongst variables’ we refer to correlational research. Correlations are used to determine to what extent two variables are related to one another. Please refer to pages 12 and 13 of your textbook. 3. We are in the process of developing a new form of medication to address the high levels of serotonin in depressive patients' brains. We have 20 participants in a control group (will not receive the drug) and 21 participants in the experimental group (will receive the drug). We plan to measure the effectiveness of the medication with a Solomon-4-group design. What type of research design is this? 1. Non-experimental research. Open Rubric 2 Questions with correct answer (in bold), explanation and references 2. Regression research. 3. True-experimental research. 4. Quasi-experimental. The question was not correctly phrased – thus none of the alternatives is correct. Therefore, this question will be credited for all students. 4. The degree of control that quasi-experimental research exerts on factors is _________. 1. low 2. very low 3. moderated to high 4. moderate Although quasi-experimental research is still criticized in the literature (based on the extent of the inferences made from results), it is widely accepted that, by using this design, researchers expect moderate to high levels of control over factors that may affect the study. Please refer to Table 1.1 on page 11 of your textbook. 5. You are required to determine employees’ perceptions of the effectiveness of the performance management system in your organisation. Your organisation only has 11 employees. Which type of research would be best suited to this research objective? 1. Descriptive. 2. Qualitative. 3. Historical. 4. Experimental research. When we want to investigate ‘perceptions’ of individuals (i.e. behaviour in specific context), we tend to use Qualitative research. Please refer to page 13 and Chapter 10 (p. 213) of your textbook. 6. Which type of research technique can be used to determine the relationship between research anxiety and academic performance? 1. ANOVA. 2. Central tendency. 3. Correlation. 4. Multiple regression. As soon as we talk ‘relationships amongst variables’ we refer to correlational research. Correlations are used to determine the extent two variables (in this case anxiety and academic performance) are related to one another. Please refer to page 12 and Chapter 8, pages 189 and 190 of your textbook. 7. Which one of the following is an example of quantitative research? 1. Interviews with a sample of engineers regarding their level of work engagement. 2. A Likert scale measuring life satisfaction of bankers. 3 Questions with correct answer (in bold), explanation and references 3. Narrative stories regarding the effectiveness of teamwork within a given department. 4. A case study to investigate the rise and fall of a business. A Likert scale (which is a type of rating scale) measuring life satisfaction of bankers will be considered quantitative research, specifically descriptive research (p. 197 of your textbook). Options 1, 3 and 4 are clear examples of qualitative research methods. 8. Which one of the following is a synonym for a dependent variable? 1. Outcome variable. 2. Treatment variable. 3. Restricting variable. 4. Threatening variable. A dependent variable is referred to as an outcome variable. Please see Table 2.1 on page 24 of your textbook. 9. Identify the dependent variable in the following hypothesis: "There will be a statistically significant difference in life satisfaction between individuals who participate in an intensive intervention program as opposed to individuals who do not participate in the intensive intervention program." 1. Participation in an intensive intervention program. 2. Participation group. 3. Individuals. 4. Life satisfaction.
