Assignment:

PART 1

1. What is the difference between a statistic and a parameter?

2. Describe what is meant by the term sampling or standard error.

3. Briefly describe a situation in which snowball sampling would be ideal for a researcher.

4. Briefly describe the importance of quality sampling with regard to issues like political polling. It would be ideal to use a very recent illustration of errors that have been made.

5. If you were tasked with creating the most representative sampling frame for residents, what would you use and why?

Part 2

1. Your research methods class has been given the assignment to measure the student body of your university with respect to their attitudes about the death penalty. To ensure equal representation of undergraduates, graduate students and all majors, what sampling technique would you use? How would you go about pulling that sample? What would you need to know before that sample is pulled?

2. Compare probability designs with non-probability designs. Identify the kinds of sampling designs available within each of these four major categories. Explain a situation in which it would be more appropriate to use probability sampling, and one where non-probability would be preferred.

3. You have been given a grant to study citizens' attitudes (in the Florence/Muscle Shoals Metropolitan Area) toward UNA with respect to noise, traffic, and minor property crimes. How would you draw a multistage cluster sample that would be representative of the Shoals?
