a. a comparison-group design.
b. time-series design.
c. participants-variable design.
d. before-after design.
Question 2

a. because they are correlational in nature, valid conclusions can never be drawn from quasi-experimental research designs.
b. quasi-experimental research will generally have higher internal validity in comparison to true experiments.
c. although they will generally have some threats to internal validity, quasi-experiments can sometimes be used to draw inferences about the causal relationships among variables.
d. quasi-experiments are less scientific than other types of research designs.
