Discussion: Categorical Data Analysis

6210 Week 11 Discussion: How To Complete The Discussion Requirement

Review the Week 11 Course Materials.

Use the General Social Survey (GSS) dataset for this Discussion

Identify a categorical (nominal or ordinal) independent variable and a categorical dependent variable.

Write a research question for a Chi-Square Test of Independence. Use this format:

- What is the relationship between (state the IV) and (state the DV)?

Write the null hypothesis. Use this format:

-There is no relationship between (state the IV) and (state the DV).

State the research design. Here are your choices:

-Descriptive

-Correlational

-Causal-Comparative/Quasi-Experimental

-Experimental

Use SPSS to answer the research question. Here’s how:

-Open the GSS data set, select Analyze, select Descriptive Statistics, select Crosstabs, drag your IV into the Rows box, drag your DV into the Columns box, Click on Statistics, select Chi-square and Phi and Cramer’s V, select Continue, select Cells, select Observed, Rows, Columns and Totals, select Continue and OK.

-Review the Asymptotic Significance value in the Pearson Chi-Square row of the Chi-Squared Tests SPSS Output and decide to reject or fail to reject the null hypothesis.

Remember, if the Sig. value is less than .05, reject the null and if the Sig. value is greater than .05, fail to reject the null.

-If you reject the null and determine that the Chi-Square is statistically significant, report and explain (weak, medium, strong) the effect size. Use the Cramer’s V value in the Symmetric Measures box for effect size

If you fail to reject the null and find that the Chi-Square is not statistically significant, then there is no need to report or explain the effect size.
