Chapter 8: Non-experimental research: Observational, Case Study, Archive Flashcards
manipulation:
in an experiment, conditions or variables assigned or presented to a participant
assignment:
in an experiment, pairing a subject with a condition or variable, according to the experimenter’s plan
observation:
the record of a behavior
Observational research takes two general forms:
naturalistic observation and participant observation, which vary in the degree of intervention by the researcher.
4 main non-experimental research methods:
observation, archival research, case studies, and surveys
The distinction between experimental research and non experimental research
1) The independent variable is not manipulated
Key words here are manipulation and assignment versus observation
2) data collection procedure often must forfeit some degree of control in return for obtaining the data
3) qualitative research interested in how individuals understand themselves and make meaning out of their lives
qualitative research:
nonexperimental research that asks questions regarding how people make meaning out of the world
correlational research:
nonexperimental research that measures two or more variables to determine the degree of relationship between them
The goals of correlational research are to describe and to predict
can determine a relationship between two variables, but cannot determine which variable is the cause and which variable is the effect
Why is non-experimental research often called correlational research?
The term is somewhat misleading, however, because all research is correlational to the extent that it seeks functional relationships between variables
What makes research correlational in the common usage is the inability to manipulate some variable independently
Experimental research frequently is done as a follow-up to previous nonexperimental observations
Observational research:
describe behaviour and, possibly, to examine the relationships among variables
can provide a rich source of hypotheses about the relationships between behaviours and the causes of behaviours. Thus, observation is often the first step in discovering the causes of behaviours
archival research:
study method that examines existing records to obtain data and test hypotheses
study crime statistics in different countries to see if there is a relation between capital punishment and the murder rate
case study:
exploratory study of an existing situation as a means of creating and testing a hypothesis
An investigator might study the victims of a natural disaster (such as the oil spill in the Gulf of Mexico) to determine its effects on their psychological health
survey:
assessing public opinion or individual characteristics by the use of questionnaire and sampling methods
hermeneutics:
the principles of interpretation of a text’s meaning
How is naturalistic observation different from the casual observation that most people do?
Naturalistic observation is research conducted in such a way that the subject’s behavior is disturbed as little as possible by the observation process. The observation is made in the environment where the behavior naturally occurs
unobtrusive research:
another term for naturalistic observation: the effort that researchers make not to influence, or obtrude on, the behavior being studied.
nonreactive research:
another term for naturalistic observation emphasizing that the subjects are unaware that they are being studied
