**Question description**

In your Week 2 Assignment, you displayed data based on a categorical variable and continuous variable from a specific dataset. In Week 3, you used the same variables as in Week 2 to perform a descriptive analysis of the data. For this Assignment, you will calculate a confidence interval in SPSS for one of the variables from your Week 2 and Week 3 Assignments.

**To prepare for this Assignment:**

- Review the Learning Resources related to probability, sampling distributions, and confidence intervals.
- For additional support, review the
**Skill Builder: Confidence Intervals**and the**Skill Builder: Sampling Distributions**, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane. - Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you chose) from Week 2.
- Choose an appropriate variable from Weeks 2 and 3 and calculate a confidence interval in SPSS.
- Once you perform your confidence interval, review Chapter 5 and 11 of the Wagner text to understand how to copy and paste your output into your Word document
- .
**For this Assignment:**Write a 2- to 3-paragraph analysis of your results and include a copy and paste of the appropriate visual display of the data into your document.Based on the results of your data in this confidence interval Assignment, provide a brief explanation of what the implications for social change might be.
