Research Design

Question 1

Experimental Research is divided in two categories:

Answer 1

True Experimental Design and Quasi-Experimental

Question 2

True Experimental

Answer 2

The investigator randomly assign subjects to different groups, which receive different levels of a manipulated variable

Question 3

Quasi-experimental

Answer 3

used when random assignment of subjects to groups is not possible

Question 4

Correlational Design

Answer 4

variables are measured rather than manipulated

Question 5

History

Answer 5

A film designed to increase the awareness of white college students is shown the day after a leading civil rights activist spoke at the college.

Question 6

In a research study testing the effects of a new strategy for increasing short-term memory, subjects have to wait 3 hours in a room before the study begins. As a result, they become very tired and cannot concentrate on learning the strategy

Answer 6

Maturation

Question 7

A drug design to improve emotional and psychosocial functioning is administered to severely depressed individuals

Answer 7

Statistical regression

Question 8

Cues in the experimental setting that allow subjects to guess the research hypothesis

Answer 8

Demand characteristics

Question 9

The effect that an experimenter expectancy has on the results of a research study

Answer 9

Rosenthal Effect

Question 10

Hawthorne Effect

Answer 10

The tendency of subject’s behavior to change due to attention received in a research setting

Question 11

Procedure designed to ensure that all subjects in a research study have an equal probability of ending up in each of the treatment groups

Answer 11

Random Assignment

Question 12

A statistical method of controlling for the effects of an extraneous variable

Answer 12

ANCOVA

Question 13

Stratified random sampling

Answer 13

A procedure that involves grouping subjects who are similar in terms of their status on an extraneous variable and then assigning the members of each group to different treatment groups

Question 14

Matching

Answer 14

A procedure in which a population is divided into sub-populations and all members of each sub-population have an equal probability of being chosen to participate in the research study

Question 15

Blocking

Answer 15

designed to determine the effects of the extraneous variable

Question 16

True-experimental research

Answer 16

Involves manipulated variables and random assignment

Question 17

Quasi-Experimetal Research

Answer 17

Involves manipulated variables and NON-random assignment

Question 18

Correlational Research

Answer 18

A study assessing the association between SAT scores and college GPA. Does NOT have internal validity

Question 19

Longitudinal design

Answer 19

A study of the effects of aging on IQ scores in which one group of subjects is examined for 30 years

Question 20

Cross-sequential

Answer 20

A study on the effects of aging on psychosocial adjustment that involves comparing older, middle aged, and younger subjects at different points of times

Question 21

Cross-sectional

Answer 21

A study on the effects of aging on psychosocial adjustment that involves comparing older, middle aged, and younger subjects at one point in time

Question 22

AB Design

Answer 22

A single subject design that involves one baseline and one treatment phase

Question 23

Reversal design

Answer 23

A single subject design in which the treatment is withdrawn to determine whether the DV score revert to baseline level

Question 24

Multiple baseline design

Answer 24

A study of a single conduct-disturbed teen in which the effectiveness of a new behavior modification program is assessed first at school, then at home, and then in the community

Question 25

Time-series design

Answer 25

A study that involves obtaining DV scores from a group of subjects on multiple occasions at regular intervals

Question 26

Case study

Answer 26

An in depth study of a single individual, institution, group, or phenomenon
