What are the 3 quantitative design concepts? (Chapter 9) - Answer Plan, structure, and
strategy
Treating facts without influence from personal feelings or prejudices (Chapter 9) - Answer
Objectivity
The measures that the researcher uses to hold the conditions of the study uniform (Chapter 9) -
Answer Control
A particular preference or point of view that is personal, rather than scientific. (distortion of the
results) (Chapter 9) - Answer Bias
All aspects of the study systematically and logically follow from the research problem (Chapter
9) - Answer Accuracy
A small study conducted as a prelude to a larger one (Chapter 9) - Answer Pilot study
The capability of the study to be successfully carried out (Chapter 9) - Answer Feasability
Interferes with the operations of the phenomena being studied (e.g. age and gender) (Chapter
9) - Answer Extraneous variable (mediating variable)
All the items in the sample are chosen because they have similar or identical traits. (e.g. people
in a homogeneous sample might share the same age, location or employment) (Chapter 9) -
Answer Homogeneous sampling
The ability of the data-collection design to hold the conditions of the study to a cookbook-like
recipe. (Chapter 9) - Answer Constancy
Test group that receives the treatment that the experiment was designed to test (Chapter 9) -
,In an experiment, the group that is not exposed to the treatment; contrasts with the
experimental group and serves as a comparison for evaluating the effect of the treatment.
(Chapter 9) - Answer Control group
A technique where the subjects do not know whether they are receiving a treatment or a
placebo. (Chapter 9) - Answer Blinding
A research design that controls for the influence of the researcher and research participants
since neither group knows which participants are in the control group and which participants
are in the experimental group. (Chapter 9) - Answer Double blinding
Each subject in a population as an equal chance of being selected and an equal chance of being
assigned to the control group or the experimental group. (Chapter 9) - Answer Randomization
The degree to which the experimental treatment, not an uncontrolled condition, resulted in the
observed effects. (Chapter 9) - Answer Internal validity
History threats
Maturation effects
Testing effects
Instrumentation threats
Diffusion of treatment
Regression towards the mean
Selection bias
Attrition (mortality) (Chapter 9) - Answer Threats to internal validity
Not only the independent variable, but also another specific event may affect the dependent
variable either inside or outside the experimental setting. (Chapter 9) - Answer History threats
Refers to the developmental, biological, or psychological processes that operate within an
individual as a function of time; these processes are external to the events of the investigation.
(Chapter 9) - Answer Maturation effects
Taking the same test repeatedly could influence participants' responses the next time the test is
completed. (the need to improve the score) (Chapter 9) - Answer Testing effects
, The loss of study participants from the first data-collection point
(pretest) to the second data-collection point (posttest) (Chapter 9) - Answer Mortality
(attrition)
The threat to internal validity that arises when pretreatment differences exist between the
experimental group and the control group - could result from the way the participants were
chosen. (Chapter 9) - Answer Selection bias
Concerns the generalizability of an investigator's findings to additional populations and to other
environmental conditions. (Chapter 9) - Answer External validity
Selection effects, reactive effects, testing effects (Chapter 9) - Answer Threats to external
validity
Concerns generalizability of the results to other populations. (Chapter 9) - Answer Selection
effects
Defined as the participants' responses to being studied. (Chapter 9) - Answer Reactive effects
Administration of a pretest in a study that affects the generalizability of the findings to other
populations. (Chapter 9) - Answer Measurement effects
The experimental factor that is manipulated; the variable whose effect is being studied.
(Chapter 10) - Answer Independent variable
The outcome factor; the variable that may change in response to manipulations of the
independent variable. (Chapter 10) - Answer Dependent variable
A design characterized by three properties: randomization, control, and manipulation) (Chapter
10) - Answer True experimental design
A design in which random assignment is not used, but the independent variable is manipulated,
and certain measures of control are used.
Use when a true experimental design can not be used because there are variables we can not
change; group/condition has been assigned by factors other than the experimenter; has
