Experimental Design

Question 1

The process of carrying out research in an objective and controlled fashion so that precision is maximized and specific conclusions can be drawn regarding a hypothesis statement.

Answer 1

Experimental Research Design

Question 2

What are the two major groups of an Experimental Research Design?

Answer 2

1. Experimental Group
2. Control Group

Question 3

This group receives the variable being tested in the experiment

Answer 3

Experimental Group

Question 4

Does not receive the variable in being tested in the experiment

Answer 4

Control Group

Question 5

Something that the researchers administer to experimental units. It is represented by the letter X.

Answer 5

Treatment

Question 6

Samples use this as one of the factors for research to become experimental. R is the letter of representation

Answer 6

Randomization

Question 7

It is the measurement used in experiments, usually a written test/questionnaire.

Answer 7

Test

Question 8

A variable that is anything held constant or limited in an experiment.

Answer 8

Control

Question 9

IT is a variable that is not of interest to the study’s aims but could influence the outcomes.

Answer 9

Control

Question 10

What are the types of experimental designs?

Answer 10

1. Pre-experiment
2. Quasi Experiment
3. True experiments

Question 11

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.

Answer 11

Pre-experiment

Question 12

This is the simplest form of experimental research design.

Answer 12

Pre-experiment

Question 13

Usually has no control group.

Answer 13

Pre-experiment

Question 14

What are the three types of pre-experimental research design?

Answer 14

A. One shot case study
B. One-group pretest-posttest
C. Static Group Comparison

Question 15

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.

Answer 15

One shot case study

Question 16

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

Answer 16

One-shot case study

Question 17

Subject are measured before and after the treatment is administered

Answer 17

One group pretest-posttest

Question 18

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

Answer 18

Static-group comparison

Question 19

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

Answer 19

Static-group comparison

Question 20

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

Answer 20

Quasi-Experiments

Question 21

Quasi means what?

Answer 21

Resemblance

Question 22

Usually quasi-experiments are in a ____ setting.

Answer 22

classroom

Question 23

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

Answer 23

True Experiments

Question 24

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

Answer 24

True Experiments

Question 25

In a true experiment, there is a ___ group.

Answer 25

Control or Comparison Group

Question 26

What are the 6 types of true experimental design?

Answer 26

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

Question 27

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

Answer 27

Posttest Only Design

Question 28

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

Answer 28

Posttest Only Design

Question 29

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

Answer 29

Pretest-Posttest-Only Design

Question 30

Both groups are measured before and after.

Answer 30

Pretest-Posttest-Only Design

Question 31

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.

Answer 31

Solomon Four Group Design

Question 32

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

Answer 32

Factorial design

Question 33

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

Answer 33

Randomized Block Design

Question 34

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

Answer 34

Randomized Block Design

Question 35

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

Answer 35

Randomized Block Design

Question 36

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

Answer 36

Cross Over Design

Question 37

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

Answer 37

Cross Over Design
