Research methods for the behavioral sciences - Chapter 6 (Gravetter
& Forzano Questions with Answers
research strategy - correct answers>>A general approach to research determined by the kind of question
that the research study hopes to answer.
research design - correct answers>>A general plan for implementing a research strategy. A research
design specifies whether the study will involve groups or individual subjects, will make comparisons
within a group or between groups, or specifies how many variables will be included in the study.
research procedure - correct answers>>The exact, step-by-step description of a specific research study.
external validity - correct answers>>The extent to which we can generalize the results of a research study
to people, settings, times, measures, and characteristics other than those used in that study.
threat to external validity - correct answers>>Any characteristic of a study that limits the ability to
generalize the results.
internal validity - correct answers>>The extent to which a research study produces a single,
unambiguous explanation for the relationship between two variables.
threat to internal validity - correct answers>>Any factor that allows for an alternative explanation for the
results of a study.
extraneous variable - correct answers>>Any variable that exists within a study other than the variables
being studied. In an experiment, any variable other than the independent and dependent variables.
confounding variable - correct answers>>An extraneous variable (usually unmonitored) that is allowed to
change systematically along with the two variables being studied. In the context of an experiment, and
extraneous variable that changes systematically along with the independent variable and has the
potential to influence the dependent variable. A confounding variable provides an alternative
explanation for the observed relationship and, therefore, is a threat to internal validity.
