SPSS data analysis assignment
The SPSS Data Analysis Assignment gives you an opportunity to work with, analyse, and report psychological data. You have been provided with a data set from a study that examines how the size of an ostracising group influences individuals? sense of belonging and self-esteem. The SPSS data file is available on the SPSS assignment section on LEO (?PSYC104 Assignment Data.sav?). At the end of this guide, you will find a skeleton lab report that includes introduction, method, and references sections. These sections give you more detail about the theoretical backgrounds, aims, and methodology, and can be directly copied into your report.
If you participated in this study, please note that the study had other aspects that we have simplified for the purposes of this assignment. For the purposes of this assignment, we are only focusing on ostracism (receiving no likes). If you did not participate in this study, your current knowledge of the study would likely influence your responses, so please do not participate in the study from this point on. If you want to know more about the method, please contact firstname.lastname@example.org. For alternative extra credit options, please contact your LICs.
Here are some guidelines for how to complete this assignment
1. Start by reading the introduction and method section provided at the end of this guide. This will give you background information about the study and details of the method. Think about how you would complete the hypotheses based on the information provided in the introduction section. Pay attention to the independent and dependent variables in the method section. Think about how you would test these hypotheses in SPSS.
2. Open the data file in SPSS.
a. Go into ?variable view? and for each variable, put in a variable label and set the type of measure. Enter labels for the values as appropriate (when we need to know what each number means). Here is more information about the variables:
? PartID is a participant ID number arbitrarily assigned by the researcher
? Age is participants? age in years
? Gender is participants? gender: 1 = male, 2 = female, 3 = other
? Grpsize is size of the ostracising group: 1 = small group, 2 = large group
? BELsc is the average of the 5 belonging items [I feel disconnected (reverse scored), I feel like an outsider (reverse scored), I feel that others interact with me a lot, I feel rejected (reverse scored), and I feel that I belong to a group]. Higher scores indicate higher levels of belonging.
? SE1-5 are the five self-esteem items: [SE1-I feel good about myself, SE2-I feel insecure (reverse scored), SE3-I feel satisfied, SE4-My self-esteem is high, SE5-I feel liked]. For all items, higher numbers indicate higher self-esteem.
b. Calculate a new variable that is the average of SE1-5. You don?t need to do any reverse scoring ? it has already been done. Just average them together. Give this variable a meaningful label and adjust the scale of measurement as needed.
c. Compute descriptive statistics for age and gender [M (SD) or N/n (%), as appropriate for each variable].
d. Conduct the necessary assumption tests for the inferential statistics you plan to use.
e. Conduct the inferential statistics that allow you to test your hypotheses (e.g., t-tests).
f. Save your SPSS data (.sav) and output (.spv) files
g. Calculate Cohen?s d for effect size (http://www.psychometrica.de/effect_size.html#cohen).
3. Create a new Microsoft Word document for your assignment.
a. Copy in the Introduction, Method, and Reference section from the end of this guide. You will add hypotheses to the introduction, participant information to the method, and then write the results and discussion section. The word limit for the new text you create (hypotheses, participants, results, discussion) is 800 words. The provided text does not add to this word count. The assignment should be presented in APA style (e.g., double-spaced, size 12 Times New Roman font), and it must use an appropriately formatted title page, headings, running head, tables and reporting style.
b. Hypotheses: In your new document, remove the research questions text and write the research hypotheses. For research question 1, develop a hypothesis that states the expected difference in belonging for participants who were ostracised by the small and large groups. For research question 2, develop a hypothesis that states the expected difference in self-esteem for participants who were ostracised by the small and large groups. Remember to state your hypotheses in terms of operationalised variables.
c. Participants: Add a participants section to the method that gives descriptive information about the sample. State how many participants took part in the study. Insert your paragraph summarising the characteristics of the sample under a Participants sub-heading within the Method section. Remember to use complete sentences when characterising the sample.
d. Results: Report the results of your analyses in a Results section.
i. Report the details of your assumption testing.
ii. Create a table to convey the descriptive statistics that map onto your inferential tests (M and SD for each DV at each level of the IV, n for each condition). Note that the table and its caption must conform to APA style. Never copy and paste a table from the SPSS output into your report.
iii. Report the results of your inferential tests (t-tests), including the t-test statement and the effect size (Cohen?s d), and reference to the relevant means that you displayed in the table. You should not repeat the numbers that were presented in the table, in the text, but you may refer to them. In your Results section, link your hypotheses to your analyses (e.g., ?To test the hypothesis that …., an independent-samples t-test was conducted comparing??);
e. Discussion: Interpret your results in a Discussion section. State the aim(s) of the study. Describe, summarise and explain the results. State whether the results are consistent with your hypotheses and the previous research summarised in the Introduction section you were provided. Provide some insight and explanation as to the relevance, importance, or implications of the findings in the context of the research questions. Identify any limitations of the study, and suggest some avenues for future research that directly follow from the limitations identified or results obtained. Finish your Discussion section with a strong concluding paragraph. You are not required to search for additional research articles.
