controlled experiment - correct answer An experiment in
which only one variable is manipulated at a time. Or
a condition that is being held constant
independent variable - correct answer what is being
changed
dependent variable - correct answer what is being
measured
control - correct answer In an experiment, the standard
that is used for comparison
Observational experiment or study - correct answer
studies attempt to understand cause-and-effect
relationships. However, unlike experiments, the
researcher is not able to control (1) how subjects
are assigned to groups and/or (2) which treatments
, WGU C165
each group receives. ... Therefore, a sample survey
is an example of an observational study.
field study - correct answer a research investigation
carried out in a naturally occurring setting
laboratory study - correct answer Research done in a
laboratory

of an object. Prototypes and appearance models are
physical models.
conceptual model - correct answer a verbal or graphical
explanation for how a system works or is organized
mathematical model - correct answer one or more
equations that represent the way a system or
process works
