Essay Instructions: Random assignment is one of the hallmarks of a classical experimental design. Visit William Trochim's Knowledge Base website to help you to understand and summarize the difference between random assignment and random sampling. Here Trochim also describes building blocks as elements of design, which ". . . provides the glue that holds the research project together." Click on the link, "Types of Designs" at the website below, read what's presented on the page, then click on "The nonequivalent Groups Design" link. You will find examples of possible outcomes from nonequivalent groups designs.
In one paragraph each, describe criminal justice examples for two possible outcomes presented.

Over the last 12-15 years, many criminal justice researchers have promoted increased use of experimental designs. This can be largely traced to the publication of Preventing Crime: What Works, What Doesn't, What's Promising (Sherman et al., 1997). One of the most interesting features of that report is a measure of the strength of research methods used by various crime prevention studies. Go to the report's website and review Chapter 2, "Thinking About Crime Prevention," by Lawrence Sherman. Also read the appendix on research methods by Sherman and Denise Gottfredson. Pay particular attention to the "scale of evidentiary strength for cause and effect." Write two paragraphs that compare how these two sections of the report use the language of research design and validity threats from this chapter of your text.

In the years since that report was published, two related organizations have been established to compile experimental studies in criminology, and publish research articles using experimental and quasi-experimental designs. The Academy of Experimental Criminology publishes the Journal of Experimental Criminology. Information about the Academy together with links to its journal and newsletter are on the Academy web page.
After browsing articles published in the journal, briefly describe two that are of interest to you. Why do you find them interesting?

Snowball sampling is a type of nonprobability sampling strategy commonly used in field research. The University of Surrey Social Research Update website presents some very useful guidelines on using snowball approaches to find hard-to-reach populations.
After reading the Update from the link below, write a couple of paragraphs to describe how you would go about selecting a snowball sample of one of the following groups: illegal street racers; marijuana dealers; graffiti artists; members of a youth gang.
See Update #33.

The Rice Virtual Lab in Statistics presents the equivalent of an online course in basic statistics. Go to the site and click on Chapter VII. Sampling Distributions. Then click on "C. Sample Size Demo." After reading the instructions, set the sample size in the middle pane to 2; then set the sample size in the bottom pane to 10. Click the "5 Samples" button near the top of your screen. Write a sentence that describes what happens to each distribution. Then click "5 Samples" 10 more times; write a sentence or two that describes what happens after 10 clicks. Click the "Reset" button near the top; then click the "10,000 Samples" button. What happens to the two distributions?
Then briefly summarize how sample size affects the distribution of sample means.

The National Archive of Criminal Justice Data (NACJD) contains criminal justice data files from numerous sources. Each data set has extensive documentation listing the source of the data, the sampling frame, the sample, and so on. You can learn more about samples, target populations, and sampling strategy by reading descriptions of data archived at NACJD.
From the website's home page, select the "Search/Browse Holdings" link near the top of the web page. Choices on the next page are inexplicably presented as "Browse BJS-funded studies" or "Browse NIJ-funded studies." You'll find greater variety in the NIJ lists, but more uniform descriptions for BJS studies. Other browse and search options are available, so start with one that seems sensible.
Scroll down the list of studies, and click on "description" for at least two. After reading the description, list the following: the population (universe), the sampling frame, the study population, the observation unit, and the sampling method that wa used to gather the sample.

Chapter 10 Writing Assignment


For a period of about three days, commit random acts of kindness. Keep a journal of your actions with the responses you received from those you helped as well as your own reactions. Focus on good deeds for strangers in the first three days (for example, give up a seat on a bus or buy a meal for a homeless person) and on family members or friends in the second three days (for example, visit an elderly relative or help a sibling/friend with homework). In your paper discuss your impressions of your experiences. Did you find yourself feeling fulfilled as a result of helping others? Did you experience any change of attitude toward those you helped? Do you feel happier now than you did at the start of the activity? Was your subjective experience the first three days (helping strangers) different from your subjective experience in the second three days (helping family or friends)? Lastly provide your own opinion on whether acts of kindness/helping are altruistic, egoistic or both?

Please make sure your paper is typed, double-spaced and in 10 or 12 point font with 1 inch margins

Essay Instructions: A professor once indicated to our class that random sampling is not important. He did not say much more about this point and many people in my class thought he was crazy. We had been repeatedly told in undergraduate classes that random sampling and random assignment were key points of research. Why would he say such a thing and what are some arguments in favor of his statement?

Additionally, what are the most important components of conducting good scientific research? That is, what do you see as the most critical aspects of having confidence in the research that you are reading?
