experiments
often considered the “gold standard” in research, experimental designs generally require subjects to be randomly assigned to a treatment or control condition
quasi-experimental designs
whereas experimental designs generally require random assignment to a treatment or control condition, quasi-experiments usually relax this requirement
survey
a form of research in which participants are asked a question or questions in order for the researchers to gather information
sample
a group of people taken from a larger population and studied or surveyed
response rate
the number of people in a survey divided by the number of people in the defined sample
field research
generally involves getting out into the environment and studying human behavior as it exists in the “real world”
pure observations
form of study in which participants do not see the researcher or even know they are being observed
participant observation
research activity where the researcher is actively involved in the behaviors being studied. For example, a recovering alcoholic researcher might study the behaviors of others in AA meetings
ethnography
the study and recording of human society and subcultures
covert observation
refers to public observation where the researcher does not let the human subjects under study know that he or she is a researcher and that they are being studied
overt observation
refers to studies in which the researcher makes human subjects aware that they are being observed
content analysis
involves reviewing records of communication and systematically searching, recording, and analyzing themes and trends in those records
operationalization
refers to the process that a researcher uses to define how a concept is measured, observed, or manipulated in a study
secondary data
data collected by other researchers that may be used or reanalyzed by another researcher
ethics in research
much effort has gone into the ethical implications of researching human subjects, which can be quite complex when studying deviant behavior. Generally, the subject should be asked if he or she consents to participate and his or her confidentiality should be protected
human subjects
living persons being observed for research purposes
institutional review boards (IRB’s)
an independent group that reviews research to protect human subjects from potential harms of the research
