Between-subjects design

Question 1

The general structure of an experiment

Answer 1

Experimental design

Question 2

A design in which different subjects take part in each condition

Answer 2

Between-subjects design

Question 3

The ideal way to recruit subjects, but is rarely achieved

Answer 3

Random selection

Question 4

A statistical estimate of size or magnitude of the treatment

Answer 4

Effect size

Question 5

The simplest experimental design used when only two treatment conditions are needed

Answer 5

Two-group design

Question 6

An experimental design in which subjects are placed in each of two treatment conditions through random assignment

Answer 6

Two-independent- groups design

Question 7

subjects are placed in each of two conditions randomly

Answer 7

Random assignment

Question 8

A treatment condition in which the researcher applies a particular value of the independent variable to the subjects

Answer 8

Experimental condition

Question 9

A condition in which subjects receive zero value of the independent variable

Answer 9

Control conditions

Question 10

A design in which two groups of subjects are exposed to different levels of the independent variable

Answer 10

Two-experimental group design

Question 11

A research design in which there are at least two groups in which one does not receive a treatment or intervention, and data are collected on the outcome measure after the treatment

Answer 11

Post-test only control group design

Question 12

Advantage of Posttest only control group design?

Answer 12

Easy to implement
Fewer resources
Eliminates threat

Question 13

Disadvantages of posttest only control group design

Answer 13

Can’t measure how much change
Mortality threat and maturation still exist

Question 14

Subjects are randomly assigned to experimental and control group and is initially tested about dependent variable of interest, experimental group is administered a treatment and the dependent variables are measured again

Answer 14

Pretest-posttest control group design

Question 15

Advantages of pretest-posttest control group design

Answer 15

Determine exact change
can eliminate threats

Question 16

Disadvantages of pretest-posttest control group design

Answer 16

More resources
Prone to identification of hypo
Prone to mortality threat, maturation, and testing threat

Question 17

A technique that maintains complete randomness of the assignment of a subject to a particular group such as flipping a coin

Answer 17

Simple randomization

Question 18

Designed to randomize participants into groups that result in equal sample sizes

Answer 18

Block randomization

Question 19

Randomization tools

Answer 19

Sealed envelope and research randomizer

Question 20

an experiment design with two treatment conditions and with subjects who are matched on a subject variable thought to be highly related to the dependent variable

Answer 20

Two-matched-groups design

Question 21

creation of pairs whose subjects have identical scores on the matching variable

Answer 21

Precision matching

Question 22

Creating pairs of subjects whose scores on the matching variable fall within a previously specified range of scores

Answer 22

Range matching

Question 23

creating matched pairs by placing subjects in order of their scores on the matching variable

Answer 23

Rank-ordered matching

Question 24

When unsure whether randomization produce an equivalent groups, especially when the sample size is small, which design should be used?

Answer 24

Two-matched groups design

Question 25

when you have identified that a subject variable is highly related to your dependent variable, this design is used

Answer 25

Two-matched groups

Question 26

A between-subjects design with one independent variable in which there are more than two treatment conditions

Answer 26

Multiple groups design

Question 27

The most commonly used multiple-groups design in which subjects are assigned to the different treatment conditions at random

Answer 27

Multiple indepedent group design

Question 28

Give two ways to assign in a multiple groups design

Answer 28

Block randomization
Web-based randomizer

Question 29

Give the variations of a multiple-independent-groups design

Answer 29

*Multiple-groups posttest-only control group design
*Multiple-groups pretest-posttest control group design

Question 30

A research design that attempts to consider the influence of pretesting on subsequent posttest results

Answer 30

Solomon four-group design
