Q

the instrument used in gathering the data must not be changed or replaced during the conduct of the study

A

instrumentation change

17
Q
  • when 1 or more subjects die, drop out, or transfer.
  • participation in the experiment is not completed
A

Mortality

18
Q

when a pretest is given to subjects who have knowledge of baseline data

A

testing

19
Q

enumerate the threats to external validity

A
  1. experimenter effect
  2. hawthorne effect
  3. measurement effect
20
Q

the characteristics of the researcher affect the behavior of the subjects/respondents

A

experimenter effect

21
Q

respondents/subjects respond artificially to the treatment because they know they are being observed as part of the research study

A

hawthorne effect

22
Q

subjects have been exposed to the treatment through taking the pretest

A

measurement effect

23
Q
  1. Subjects are randomly assigned to groups
  2. A pretest is given to both groups.
  3. The experimental group receives the treatment while the control group does not
  4. A posttest is given to both groups
A

PRETEST-POSTTEST CONTROLLED GROUP DESIGN

24
Q
  1. Subjects are randomly assigned to groups
  2. The experimental group receives the treatment while the control group does not.
  3. A posttest is given to both groups.
A

POSTTEST CONTROLLED GROUP DESIGN

25
Q
  1. Subjects are randomly assigned to groups
  2. Two of the groups (experimental group 1 and control group 1) are pretested.
  3. The other two groups (experimental group 2 and control group 2) receive the routine treatment or no treatment. 4. A posttest is given to all four groups
A

SOLOMON FOUR-GROUP DESIGN

26
Q

In this design, it is either no control group or the subject are not randomly assigned to groups.

A

Quasi-Experimental Design

27
Q

No random assignment of subjects to the experimental and control groups.

A

Non-Equivalent Controlled Group Design

28
Q

The researcher periodically observes or measures the subjects.

A

Time-Series Design

29
Q

In this design, the researcher has little control over the research which makes this design to be weak.

A

Pre-Experimental Design

30
Q

A single group is exposed to an experimental treatment then the researcher will observe the group after the treatment.

A

One-Shot Case Study

31
Q

The researcher provides comparative description of a group of subjects before and after the experimental treatment.

A

One-Group Pretest-Posttest Design

32
Q

Quantitative Research Designs

A
  • Experimental Research Design
  • Non-experimental Research Design
33
Q

Experimental Research Designs

A
  • True Experimental Design
  • Quasi-Experimental Design
  • Pre-Experimental Design
34
Q

True Experimental Designs

A
  • Pretest-posttest controlled group deisgn
  • Posttest only controlled group design
  • Solomon four-group design
35
Q

Pretest and posttest have..?

A

Multiple observations

36
Q

Pre-experimental designs

A
  • One-shot case study
  • One-group pretest-posttest design
