Experimental Design Types – Practice Flashcards

These flashcards review key experimental and quasi-experimental research designs, helping you recognize how participants are assigned and measured in different study structures.

What design randomly assigns participants to treatments without considering any blocking factors?

Completely Randomized Design

Which design first groups participants into homogeneous blocks (e.g., grade level) and then randomly assigns treatments within each block?

Randomized Block Design

In what design does every participant experience every combination of two or more factors (e.g., music × caffeine)?

Factorial Within-Subjects Design

What design combines a between-subjects factor (e.g., gender) with a within-subjects factor (e.g., lesson type) in the same study?

Factorial Mixed Design

Which design uses a square arrangement so each treatment appears exactly once in every row and column, controlling for two blocking variables?

Latin Square Design

What design measures the same individual repeatedly over time or conditions to examine change (e.g., 9 a.m., 1 p.m., 5 p.m.)?

Repeated Measures Design

If every participant experiences both versions of an app (game mode and quiz mode) in succession, what design is being used?

Within-Subjects Design (Repeated Measures)

When two separate groups are randomly assigned to different study methods and compared on a single post-test, what design is this?

Between-Subjects Design

What design assesses one group before and after an intervention to detect improvement (pre-test → instruction → post-test)?

Pretest-Posttest Design

A study administers only a post-test to one group after a new revision technique, with no pre-test or control group. What is this design called?

Posttest-Only Design

When two non-randomly formed groups receive different treatments and are compared on a single post-test, what design is used?

Posttest with Non-Equivalent Groups Design (Quasi-Experimental)

Two non-equivalent groups both take a pre-test and a post-test around an intervention applied to only one group. What design is this?

Pretest-Posttest with Non-Equivalent Groups Design

A study that measures participants on three diet types and three exercise routines without including every possible combination but ensuring each treatment appears once per row and column illustrates what design principle?

Latin Square Design (Balancing Treatments Across Rows and Columns)
