SOCY 2112 Research Methods II

Let's say that we're studying household size in Kings County. The mean HH size is 4.2 persons, with a standard deviation of 1.8 persons.

Calculate the Z-test and determine the probability of the following outcomes. The mean occupational prestige score in Kings County in 2013 is 44.8. The population standard deviation is 18.3. Each group will demonstrate their work on the whiteboard.

Calculate the standard score (Z) and determine the probability for the following conditions. The mean hourly wage for New Yorkers with a college degree is $18.25. The population standard deviation is $11.80. Each group will demonstrate their work on the whiteboard.

Compose your answers in a Word/Pages/Google document (or the equivalent kind of file) and email prior to the due date or print and bring to class on the due date. Test your code in R before submitting your lab, so that you know it is correct.
Be careful to write the code exactly, or copy the code from the R console into your word processor to ensure accuracy.

1. Identify a categorical variable that you think would explain some variation in favorability toward the police. Compute descriptive statistics (mean, median, standard deviation) and interpret the results.

Pose a question about the conceptual material that we've covered so far. Your question should be one that can be correctly answered in a single paragraph. Make a case for why we should include this question on the exam.

Pose a sociological question regarding group differences, and select appropriate variables in ANES 2016 to test for the causal effect. Interpret the results. You may need to recode. Paste your R code below your interpretation.

Compute central tendency and variability for a dependent variable by ethnic identity and interpret the results. Copy your R code below your interpretation in a comment to this page.

We'll need to rearrange the schedule a bit to take account of the days we missed because of my absences. I"ll give you additional time on lab #2, in case there are questions about crosstabulations and odds. Lab #2 will be due on Monday, 3/5. We'll keep the midterm as scheduled for next Wednesday, 3/7. I'll move the due date for lab #3, on descriptive statistics, to the week following the midterm, so that we'll have time to cover the material. Lab #3 will be due on W 3/14. We'll finish up descriptive statistics on M 3/5, and have time for a review session for the exam.

Select a different measure of political participation and produce a percentage table and interpret the probabilities. Then recode it into a 2x2 table and compute the odds ratio and interpret the results. Post your interpretations and your R code as a comment to this page.

Be careful to write the code exactly, or copy the code from the R console into your word processor to ensure accuracy.

1. Formulate a sociological question and find two categorical variables in the ANES 2016 to test it. Identify the question and the variables:
