Assignment - Criminal justice questions

1. Persons who work in law enforcement typically use the term recidivism to describe some type of return to criminal behavior. Why has it been so difficult to define and measure this behavior? Examples would help here, as discussed in class.

2. Discuss three of the following methods for measuring crime in the United States. Make sure you address specifically, a) the Uniform Crime Reports (UCR); and b) National Crime Victimization Survey. For the third method, be sure to comment on either self-report surveys of high school seniors or household populations as we have discussed in class. For each method you select, be sure to address: what they measure; type of data collected; the sample involved, and any limitations, particularly any bias in the sample.

3. What are the three elements of, and the sequence of, an experimental design? Illustrate by providing an example.

4. How and why are experimental designs superior to observational or quasi experimental ones (that is, designs that do not have random assignment of subjects or other units of analysis to treatment conditions)?

5. Name one threat to the internal validity of an experimental design that is particularly problematic, as discussed in class. Discuss ways in which this serious threat can be minimized.
