Q

These happen before the true experiment start. This is done to determine the researchers’ intervention on a group of people. These will help them tell if the investment of cost and time for conducting a true experiment is worth while.

Q

A type of pre-experimental design where a single group of test units is exposed to a treatment and a single measurement is taken afterwards.

16
Q

It only measures the post-test results and does not use a control group

A

One-shot case study

17
Q

Subject are measured before and after the treatment is administered

A

One group pretest-posttest

18
Q

Uses 2 groups with different treatments. After the treatment, a test will be given.

A

Static-group comparison

19
Q

The control group is measured without having been exposed to treatment.

A

Static-group comparison

20
Q

Studies that aim to evaluate interventions but that do not use randomization

A

Quasi-Experiments

21
Q

Quasi means what?

A

Resemblance

22
Q

Usually quasi-experiments are in a ____ setting.

A

classroom

23
Q

Helps investigate the cause-and-effect relationships between the variables under study.

A

True Experiments

24
Q

The key of this resesrch is “random assignment of subjects” to treatment groups.

A

True Experiments

25
Q

In a true experiment, there is a ___ group.

A

Control or Comparison Group

26
Q

What are the 6 types of true experimental design?

A

A. Posttest only design
B. Pretest-Posttest-Only Design
C. Solomon Four Group Design
D. Factorial Design
E. Randomized Block Design
F. Cross Over Design

27
Q

Type of true experimental design where test units are randomly allocated to an experimental group and a control group.

A

Posttest Only Design

28
Q

The experimental group is exposed to a treatment and both groups are measured afterwards.

A

Posttest Only Design

29
Q

A type of true experimental design where test units are randomly assigned to an experimental group and a control group.

A

Pretest-Posttest-Only Design

30
Q

Both groups are measured before and after.

A

Pretest-Posttest-Only Design

31
Q

The researcher uses four groups. Two groups are treated as they would be in a classic experiment - pretest, experimental group intervention, and post test.

The other two groups do not receive the pretest, though one receives the intervention. All groups are given the post-test.

A

Solomon Four Group Design

32
Q

Most common is the 2x2 design. This type of study involves two factors (or two independent variables) and each factor has two levels.

A

Factorial design

33
Q

An experimental design where the experimental units are in groups called blocks.

A

Randomized Block Design

34
Q

The treatments are randomly allocated to the experimental units inside each block.

A

Randomized Block Design

35
Q

When all treatments appear at least once in each bloc, we have a completely randomized block design.

A

Randomized Block Design

36
Q

Study participant receives all treatments that are being investigated but at different times.

A

Cross Over Design

37
Q

With this type of study, every patient acts as his or her own control.

A

Cross Over Design
