For the computer homework questions, please use the report format:

First, answer the questions in complete sentences, using the output text

or figures as evidence to support your answer; then, attach the program

codes (with comments to code more readable) as an appendix by the

end of the statistical report. When you copy and paste the text part,

please box them and treat them as tables. Please label all your figures

and tables. The code in your appendix may contain extra code you have

used or explored, but should be executable (no errors).

SPSS Data Analysis Assignment Guide

Worth 30%

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. 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.

Note: Please refer to tutorial notes for SPSS (SPSS file is not the same shown in tutorial notes).

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.
    1. 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.


  1. 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.
  2. Compute descriptive statistics for age and gender [M (SD) or N/n (%), as appropriate for each variable].
  3. Conduct the necessary assumption tests for the inferential statistics you plan to use.
  4. Conduct the inferential statistics that allow you to test your hypotheses (e.g., t-tests).
  5. Save your SPSS data (.sav) and output (.spv) files (NEED TO UPLOAD BOTH FILES)
  6. Calculate Cohen’s d for effect size (http://www.psychometrica.de/effect_size.html#cohen).
  1. Create a new Microsoft Word document for your assignment.
    1. 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.
    2. 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.
    3. 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.
    4. Results: Report the results of your analyses in a Results section.
      1. Report the details of your assumption testing.
      2. 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.
  • 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…”);
  1. 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.
  1. This report will be submitted electronically using the Turnitin link on the SPSS assignment section. You will need to submit three separate files in the appropriate tabs in turnitin.
  2. the electronic version of the report that is handed in (word or pdf file)
  3. The SPSS data file with all appropriate labels (.sav file)
  4. The SPSS output file with all output that is used in the report (.spv file)

SPSS Analysis

1) For the variable HOME, what are the modes? Is the data normally distributed?



2) For the variable ARREST, what are the modes? Is the data normally distributed?


3) Why are we concerned about the distribution of data?



4) What difference does it make in the case of each of the variables (HOME and ARREST) if the data is not normally distributed?

All of the questions refer to the results of the SPSS analysis presented on pages 161-165 of the textbook.
