PSY 3901_ Applied Final Exam Response Sheet

Abstract

PSY3901: Experimental Psychology 1 Applied Final Exam Response Sheet NAME: Instructions: Your applied final exam presents you with four different applied research examples. The methodology and data for each of these four research problems are described in detail on your PSY3901 Applied Final Exam Instructions file. Read through a research problem and then complete the exam research tasks and response questions related to that research problem included on this response sheet below. The final exam includes a total of 25 questions worth a total of 200 points (20%) toward your final grade in the course. The amount of points each question is worth is displayed alongside each question. Some exam questions instruct you to perform tasks in SPSS and provide the output you generated. For each of these questions, copy and paste the output in the space provided below each question. For questions requiring written responses, provide complete written answers in the space provided below each question. Each exam question appears on its own page in this document to help you keep your exam responses organized. Provide your SPSS output or written response below each question on the same page. Research Problem 1: Big-Five Personality Traits and Optimism Use the Research Problem 1 description and the BigFive_Optimism.sav SPSS dataset to complete the instructed tasks and obtain statistics needed to answer exam questions 1–12 included below. QUESTION 1 3 points How many males and how many females were included in the sample of 95 participants? (Hint: Request frequency tables on participant sex in SPSS.) QUESTION 1 RESPONSE QUESTION 2 3 points What percentage of the sample identified their ethnicity as African American/Black? (Hint: Request frequency tables on participant ethnicity in SPSS.) QUESTION 2 RESPONSE QUESTION 3 6 points Summarize the age characteristics in the sample of 95 participants. In your response include each of the following: The range of ages represented in the sample The mean, median, and mode The standard deviation Description of the shape of the distribution of age (Hint: Request descriptive statistics on participant age in SPSS.) QUESTION 3 RESPONSE QUESTION 4 4 points Assume any participant who had an Optimism score less than 18 (i.e., had a score of 17 or lower) was categorized as pessimistic. How many participants in our sample would be considered pessimistic? )Hint: Request frequency tables on Optimism in SPSS.) QUESTION 4 RESPONSE QUESTION 5 6 points Obtain the means and standard deviations for the measures of the Big-Five personality traits and optimism in SPSS. Use the descriptive data to fill in Table 1 below. Round each statistic to two decimal places. QUESTION 5 RESPONSE Table 1. Means and Standard Deviations for Measures of Big-Five Personality Traits and Optimism Measure M SD Extraversion Agreeableness Conscientiousness Neuroticism Openness Optimism QUESTION 6 8 points Conduct an independent-samples t-test in SPSS to examine if there are any sex differences in neuroticism scores. Copy and paste (or import) the t-test output below. QUESTION 6: Paste SPSS Output Below QUESTION 7 12 points Summarize the results of the t-test output provided for Question 6 above. In your summary, be sure to address the following: Indicate if the assumption of homogeneity of variance was met Interpret the t-test results and report the results in correct statistical notation Report the mean and standard deviation neuroticism scores for males and females and interpret the findings (i.e., did males or females have higher neuroticism scores than the other sex?) Report and interpret an appropriate measure of effect size QUESTION 7 RESPONSE QUESTION 8 8 points Obtain Pearson correlation coefficients in SPSS to examine the relationships between extraversion, agreeableness, conscientiousness, neuroticism, openness, and optimism. Copy and paste (or import) the Pearson correlation matrix output below. (Hint: In the Bivariate Correlations menu in SPSS, include all six variables to create a correlation coefficient matrix in your output.) QUESTION 8: Paste SPSS Output Below QUESTION 9 12 points Using the correlation output provided for Question 8 above, interpret and report the correlations between each of the Big-Five personality factors (extraversion, agreeableness, conscientiousness, neuroticism, openness) and the optimism variable. Describe which of the Big-Five personality factors are significantly correlated with optimism, and interpret the direction and strength of each relationship. QUESTION 9 RESPONSE QUESTION 10 8 points Use SPSS Chart Builder to create a Simple Scatterplot depicting the linear relationship between extraversion and optimism. After producing the scatterplot figure, use the SPSS chart editor to add the regression line and coefficient of determination (r2). Paste the final scatterplot figure below and include an APA-style title. QUESTION 10: Paste Figure Below QUESTION 11 8 points Conduct a simple linear regression in SPSS with one predictor examining if extraversion is a predictor of optimism (outcome variable). When specifying the analysis in SPSS, include Extraversion as an Independent(s) and Optimism as a Dependent. Copy and paste (or import) the regression output below. QUESTION 11: Paste SPSS Output Below QUESTION 12 12 points Using the regression output provided for Question 11 above, summarize the results of the regression analysis that examined if extraversion was a significant predictor of optimism. Report and interpret the R Square of the model. Also, report the ANOVA table results and the standardized coefficient weight (Beta) for the extraversion score. Finally, provide at least one sentence interpreting the findings (i.e., is having an extraverted personality...
