Crowdly

If Tanisha made use of random assignment, this means that every participant in her study:

had an equal chance of being assigned to any particular group or condition of her study

was perfectly matched with another participant in the study

was assigned to a different control condition in the study

participated in every condition of the study

Compared with true experiments, quasi-experimental designs provide researchers with greater:

evidence of group differences

external validity

evidence of causality

control of procedural confounds

Which of the following is NOT true of quasi-experiments?

They can often be conducted when true experiments cannot.

The presence of confounded variables can reduce internal validity.

They provide researchers with complete control over all aspects of the independent variable(s).

The external validity of quasi-experiments is often higher than that of true experiments.

Which of the following is an essential characteristic of a true experiment?

heterogeneous attrition

measurement

random assignment to groups or conditions

sample size

Compared with other research designs (e.g., quasi-experimental designs), true experiments provide researchers with superior information about:

procedural confounds

group differences

causality

experimental artifacts

A research design in which someone tests a claim about a variable by exposing something to a person and saying that the person thought, felt, or behaved as expected is referred to as:

a clinical trial

a quasi-experiment

an experiment

a pseudo-experiment

Which of the following techniques can increase the population validity of an experiment?

Random assignment

Random sampling

Counterbalancing

Control groups

Which of the following issues can be controlled for by using a control group in a research design?

Artifacts

Non-random assignment

Systematic individual differences

The Hawthorne effect

If I was interested in testing a new drug for depression using depressed and non-depressed groups, the quasi-experimental design I would most be most likely to use would be:

Natural Experiment

Within subject experiment

attribute-by-treatment quasi-experiment

Quasi-IV only experiment
