One-shot experimental case study

One-group pretest-posttest design

Static group comparison

Pretest-posttest control group design

Solomon four-group design

Posttest-only control group design

Within-subjects design

Nonrandomized control group pretest-posttest design

Simple time-series design

Control group, time series design

A.

Participants are not randomly assigned and two groups are observed—once before the treatment is administered to the experimental group and once after.

B.

An experimental group receives the treatment and the control group does not. Then, each group is observed after the treatment is administered.

C.

Subjects within one group serve as the experimental group and the control group since they are observed with and without the treatment.

D.

A quasi-experimental design with one group, a series of observations occur, then a treatment is administered or other new dynamic, and then additional observations occur.

E.

Possibly the most primitive form of experiment while being consideredresearch.

F.

A pretest-posttest design with the addition of two groups who do not receive a pretest.

G.

An experimental group and control group are observed, the treatment is administered to the experimental group, and then both groups are observed again.

H.

An experimental design with random assignment of groups, the treatment is administered to the experimental group and not the control group, and then each group is observed.

I.

A single group is observed prior to manipulating the independent variable, the treatment is administered, and the group is observed post-treatment.

J.

Like the Simple time series design while including two groups—experimental and control.
