ASSESSMENT 2: SUBMISSION TEMPLATE
Questions
1. Describe three different situations where it would be appropriate to conduct hierarchical regression to answer a research question. Then, describe one potential disadvantage or pitfall of using hierarchical regression rather than entering all variables into the regression simultaneously. (1-2 paragraphs) [4 marks]
Write your answer here.
2. Conduct the appropriate test to predict classification as having a secure or insecure attachment style based on relationship satisfaction, life stress, and parental divorce during childhood. Use the results to answer the following questions:
a. How well has the model performed? Identify the percentage of variance that has been accounted for, and the proportion of cases that it successfully predicts. Justify your answers. (2-3 sentences) [2 marks]
Write your answer here.
b. Report and interpret the results for each of the three predictors according to APA guidelines. (1 paragraph) [3 marks]
Write your answer here.
3. Conduct the appropriate test to determine to what extent the relationship between stress and relationship satisfaction can be accounted for by maladaptive coping behaviours.
a. As part of conducting this test, generate a diagram of the model in JASP and include it with your results. Give the image an appropriate figure title. [1 mark]
Include your figure title and diagram here.
a. Report and interpret the results according to APA guidelines, referring to the image included in Question 3a. (1 paragraph) [3 marks]
Write your answer here.
b. Briefly summarise the nature of the indirect effect according to magnitude and direction of the path coefficients in your path diagram. How is stress related to coping behaviours, and how are coping behaviours related to relationship satisfaction? (2-4 sentences) [1 mark]
Write your answer here.
4. Conduct the appropriate test to determine whether the relationship between stress and relationship satisfaction varies according to secure vs. insecure classification status.
a. How much additional variance was explained by adding the product term in the second step of the model? Justify your answer. (2 sentences) [1 mark]
Write your answer here.
b. Generate a graph of the association between stress and relationship satisfaction separately for secure and insecure participants using the ‘Descriptives’ menu option in JASP and include it with your results. Give the image an appropriate figure title. [1 mark]
Include your figure title and graph here.
c. Report and interpret the results according to APA guidelines, referring to the image included in Question 4b. (2 paragraphs) [3 marks]
Write your answer here.
5. Conduct the appropriate test to determine whether attachment style influenced the speed at which participants responded “Yes” to sentences that represented insecure attachment after including social support as a covariate.
a. Evaluate the assumption of independence of the covariate and predictor. Identify the test you have used to do this, and whether the assumption is met. Justify your answer. (2-3 sentences) [2 marks]
Write your answer here.
b. Report and interpret the results of this test according to APA guidelines. (1 paragraph) [3 marks]
Write your answer here.
6. Conduct the appropriate test to investigate how the dependent variables of life stress and relationship satisfaction differed based on attachment style and parental divorce.
a. Evaluate the assumptions of multivariate normality and homogeneity of covariance matrices for this test. Identify the tests you have used to do this, and whether the assumptions are met. Justify your answer. (2-4 sentences) [2 marks]
Write your answer here.
b. Report and interpret the results of this test according to APA guidelines. Include the results of the appropriate post-hoc test available in JASP. (1 paragraph) [3 marks]
Write your answer here.
7. Conduct the appropriate test to determine the impact that agreement vs. disagreement and secure vs. insecure descriptions had on reaction time.
a. As part of conducting this test, generate a graph displaying the means in each condition and include it with your results. Give the image an appropriate figure title. [1 mark]
Include your figure title and graph here.
b. Report and interpret the results of this test according to APA guidelines, referring to the image included in Question 7a. (1 paragraph) [3 marks]
Write your answer here.
8. Conduct the appropriate test to add the participant’s attachment style as an additional explanatory variable to the analysis from Question 7.
a. Evaluate the homogeneity of variance assumption for this test. Identify the test you have used to do this, and whether the assumption is met. Justify your answer. (2-3 sentences) [1 mark]
Write your answer here.
b. To aid your interpretation of the test, generate a graph of the means in each condition, as you did for Question 7a. This time, however, generate separate plots for secure and insecure participants. Give the image an appropriate figure title. [1 mark]
Include your figure title and graph here.
a. Report and interpret the results of this test according to APA guidelines, referring to the image included in Question 8b. (2 paragraphs) [3 marks]
Write your answer here.
b. Provide a brief summary of the interaction effects identified. What does this indicate about the study’s key research hypothesis? (That is, the hypothesis that securely attached participants would be faster to accept secure descriptions and faster to reject insecure descriptions, whereas insecurely attached participants would be faster to accept insecure descriptions and faster to reject secure descriptions.) (3-5 sentences) [2 marks]
