c. an experimental design with only an experimental group and a posttest, no pretest.
d. a pre-experimental design that has one group, a pretest, treatment, and a posttest. It lacks a control group and random assignment
e. an experimental design in which the dependent variable is measured periodically across many time points, and the treatment occurs in the midst of such measures, often only once
