Case Study - ANSWER- A method that involves obtaining an in-depth analysis of a
single "case". Historically used in clinical settings (i.e. HIV research)
Observational Study - ANSWER- A method that involves observing people, animals, or
any phenomenon. Two settings; naturalistic observation or lab study
Survey - ANSWER- Relies on participants for answers to investigate whether there is a
relationship between two or more questions asked
Positive correlation - ANSWER- A similar change between two variables (i.e. more
study time = higher GPA)
Negative correlation - ANSWER- An inverse change between two variables (i.e. more
TV time = lower GPA)
Experiment - ANSWER- A method that involves manipulating (changing) the
independent variable to see if this change results in a change to the dependent variable
Independent variable - ANSWER- Also called the "predictor" variable. What is
manipulated by the researcher
Dependent variable - ANSWER- Also called the "outcome" variable. What is measured
by the researcher
How do researchers manipulate the independent variable? - ANSWER- Creating a
treatment or a workshop
Quasi experiment - ANSWER- A method that enables a researcher to test a casual
hypothesis/research question. Much like an experiment, however, assignment is tightly
controlled
What is the difference between an experiment and a quasi experiment? - ANSWER-
Quasi experiments do not include random assignment
What is the difference between random assignment and random selection? - ANSWER-
Random selection focuses on how you got your participants, while random assignment
focuses on how you assigned the selected participants to the treatment
Is random selection necessary in an experiment or a quasi-experiment? - ANSWER-
NO!
