SOCI 332

Statistics for Social Sciences

Need SPSS software & GSS (free to download )

Week 1:Choose a topic that you would like to research this term. Use the GSS database to find two variables that would support your topic – one independent variable and one dependent variable. Be sure to include the topic, variable names and description in your post. Then discuss how you hope to explore the variables this term and what you hope to learn.

Example:

Does people’s education level affect their income? Independent variable (IV) is education level – the variable DEGREE. Dependent variable (DV) is income – the variable RINCOM16.

Week 5:Analyzing the methods of peer-reviewed study

Find and read a quantitative peer-reviewed journal article that relates to your topic in which the researchers use existing data (a dataset versus collecting their own data). What information about the dataset do the researchers include? How do they describe their research methods? Which variables do they analyze and why? What are their hypotheses? What statistical analyses so they use?

Explain why discussing the data and methods is important to establish the validity and reliability of the research. Discuss any critiques you have of the Methods/Data section of the article. Are they missing any information that would be useful to the understanding of the research? (Include an APA citation of the article.)

Week 8: your findings

We finally made it!  Now it is time to share with the class what you have found about your particular topic. You’ve worked too hard on this project to only share its completion with your instructor — sharing with our whole class is a positive and empowering way to end the class.  SHAPE  \* MERGEFORMAT

Take your Week 7 Final Project Assignment and digest it in a presentation format.  Create a narrated multimedia presentation using either Power Point, Screencast-o-matic, or Prezi.  Remember, narration with audio (not just ppt notes) is necessary.  In essence, your presentations should “play” for us.  The presentation should be no more than 5-10 minutes (about 8-10 slides).  Be sure to provide some background on the topic, discuss your variables (including frequency tables/charts), include the steps of hypothesis testing, provide figures (crosstabs, measures of association, and tests of significance) and discuss them, and conclude by highlighting how your research fits into the existing body of literature on this topic.

Lastly, take the time to view what your classmates have done and leave constructive feedback based on your review.

Week 2: Frequencies and DescrriptivesPrior to completing this week’s discussion, you must have SPSS rented and downloaded. You must also have the GSS dataset downloaded from the SPSS & GSS Overview and saved to your computer. You will first open SPSS and then open the GSS dataset within SPSS. (See Intro to SPSS.)

You are now going to create and post a frequency table, chart, and descriptives table (central tendency/dispersion) of each of your variables. 

Complete the following steps:

  1. Post a brief explanation of your topic. Include your research question and for each variable – the name, survey question or description, answer categories (yes/no, strongly agree, disagree, etc.), and level of measurement (nominal, ordinal, or interval/ratio)
  2. Include a frequency table for each of your variables. Explain your outputs in no more than 5 sentences for each variable. Cite numbers in the outputs to support your conclusion. When you cite %, use the % reported in the “valid percent” column.
  3. Create a chart for each variable, which is a graphic representation of your data. The type of chart (pie, bar, or histogram) is based on a variable’s level of measurement. Explain your outputs for each variable. It is OK if your explanation is similar to (but not the same as) the frequency table interpretation since a chart is a different data presentation on the SAME variable. Cite numbers in the outputs to support your conclusion.
  4. Describe the measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation) for each of your variables. Based on what you have learned in the readings and lessons this week, identify the best measures for each variable and explain what they tell us. What do these measures summarize for us about the variable’s data?

Copy all of the frequency tables and charts into the discussion window or into a document (PDF, MS Word) and attach to discussion. If your table/chart does not fit to the page, choose “copy special” and then “images” or take a screen shot of the table/chart to copy/past into the window.

Week 3: CrosstabsIn our lessons this week, we discuss the use of crosstabulations (crosstabs) as a preliminary analysis to begin investigating the relationship between the IV and DV. A crosstab creates a “snapshot” of our data. Measures of association help to identify the strength and direction of the potential relationship.

You are now going to create and post a crosstab of your variables and a measures of association table. 

Complete the following steps:

  1. Post a brief explanation of your topic. Include your research question and a broad research hypothesis — that is, the relationship of IV to DV. (For example, educational attainment affects family income in US adults.)
  2. Run a crosstab on your variables.  Be sure to explain your findings, including a description of the table, a calculation of the epsilons, and a discussion of the 10% rule.
  3. Run the correct measure of association for your variables (Choose one – either Pearson R, Gamma, Phi, Cramer’s V or Lambda). Explain what the output means in terms of strength and direction of the relationship. Interpret Proportional Reduction of Error (PRE) using the following statement: Knowing the IV will reduce error in predicting the DV by *%.

Copy the crosstab and measure of association table into the discussion window or into a document (PDF, MS Word) and attach to discussion. If your table does not fit to the page, choose “copy special” and then “images” or take a screen shot of the table to copy/past into the window.

Special note:

When a variable is continuous (interval/ratio level of measurement), for example age of respondent, we do not run crosstabs directly because it will result in a really spread-out table with lots of zeros and low frequency cells. Such a crosstab does not help us understand the data. The correct way is to reduce the level of measurement to either ordinal level or nominal level (group the numbers into categories) by recoding and then run the crosstab. (Please refer to the Lesson Recoding in SPSS for further information.)

As a reminder, here are the guidelines for choosing your measure of association:

  1. Both DV and IV are nominal variables: Lambda (when it is not a 2X2 table)
  2. Both DV and IV are nominal variables and it is a 2X2 table: Phi
  3. Both DV and IV are ordinal variables: Gamma
  4. One variable ordinal or interval/ratio AND the other variable dichotomous nominal (like Yes/No, male/female, etc.): Gamma
  5. One variable ordinal or interval/ratio AND the other variable nominal (not dichotomous, has more than 2 categories): Cramer’s V.
  6. Both DV and IV are I/R variables: Pearson’s r

Week 6: test of significanceIn Week 3, we used crosstabs to determine if a potential relationship between two variables is worth examining further. During Week 4, we studied tests of significance. In this week’s discussion, students will apply these tests of significance to their project variables. As we discussed previously, the level of measurement of our variables determine which test of significance works for the research project.

Complete the following steps:

  1. Post a brief explanation of your topic. Include your research question. Next, begin your 5 steps of hypothesis testing by stating your research and null hypotheses. State your alpha level is .05.
  2. Run a test of significance on your variables (based on the level of measurement).  Copy and paste the appropriate table into the window.
  3. Identify the two-tailed p value and explain your findings. Is p

As a reminder, here is the guideline for tests of significance: 

1. IV and DV are BOTH categorical variables (nominal/ordinal): Chi-square

2. IV and DV are both interval/ratio variables: Regression

3. IV is categorical (nominal/ordinal) and DV is interval/ratio:

           a. IV has 2 values/groups: Independent Sample T-test

           b. IV has 3 or more values/groups: ANOVA

Why do we need to run tests of significance?

  1. They allow us to see if our relationship is “statistically significant.” To be more specific, these tests tell us if a relationship observed in a sample, like our research project based on GSS 2018 data set, is generalizable to the population from which this sample was drawn (US adults).
  2. Test results reported under “p” in the SPSS output tell us the probability or likelihood that a relationship observed in the sample is not real, but rather due to factors like a sampling error or chance. We compare this “chance” with alpha (level of significance), commonly set as .05 or .01. If this chance is smaller than level of significance (p
