1. Discuss the major disadvantages of the Uniform crime report as a source of crime. What do you understand by the term “dark figure of crime”? The Uniform Crime Report has been the primary source of official crime statistic since 1930; participation of this program is voluntary, furthermore all agencies do not participate. The Uniform Crime Report, report crimes to the nation’s police and sheriff’s departments. They separate crime into two categories: Part I Offenses, where four violent crimes are included (assault, homicide, forcible rape, and robbery), and four property offenses (larceny/theft, burglary, motor vehicle theft, and arson). Part II Offenses, where “less serious crimes” such as running away, gambling, “victimless” crimes,…show more content…
Scientifics use the quasi experimentation to look for cause and effect, when a controlled experiment is impossible because of ethics, money or time are not available. Just like any other experiment they have the independent and dependent and independent variable, however since is not a true experiment Scientifics often use the term predictor variable referring to the independent variable and criterion variable to refer to the dependent variable (Carlo et al., 1998, 278). In addition to the alternate term for variables, since in most quasi experiments there are not experimental or controlled groups, Scientifics use the terms exposure group to represent the experimental group, and comparison group to represent the control group (Rossi & Freeman, 1989,…show more content…
In experimental researches, a scientist would systematically manipulate a suspected “causal variable” and then monitors the suspected “effect variable” to determine if it changes as expected (Stroebe & Diehl, 1991). Other characteristics of controlled experiments are that scientist use independent and dependent variables and they also use two groups of subjects, experimental (exposed to the independent variable to an unusual degree) and the control group (exposed to the independent variable to a normal degree). Controlled experiments have four main types of experimental designs: 1. Classical experimental: subjects are randomly assigned to one of two groups, and they also have two time frames. 2. After-only experimental: must have two groups of subjects, and no observation occurs prior to the time the independent variable is imposed on the experimental group. 3. Before-after no control experimentation: the only experimental design where there is only one group of subjects, all of whom will be exposed to the independent variable. 4. Cross over: it’s rarely used in social science experiments; the main idea is that at some point in time all participants serve as both experimental subjects and
