Psychological Research Methods Quiz Questions

The effect of one factor within a level of another factor

When each level of an independent variable effects the dependent variable differently

Differences on the dependent variable across the levels of one

The probability that the experimenter made a type 1 error in at least one of the comparisons

Complex comparisons where more than two means are compared at the same time

Means comparisons that take into account experiment-wise alpha

Which means differ significantly from one another

When one condition mean is compared with another condition mean

Some factors are between subjects and some are within subjects

Conclusions are incorrect because a type I or II error was made

The measured variables do not relate to the conceptual variables

The dependent variable was changed by a confounding variable

The observed effects can be found only under very limited conditions

Conclusions are incorrect because a type I or II error was made

The measured variables do not relate to the conceptual variables

The dependent variable was changed by a confounding variable

The observed effects can be found only under very limited conditions

Random error may increase the likelihood of a type II error may reduce power

Systematic error, which provides an alternative explanation for the results

The extent to which the manipulation involves the participants in the research

When expectations effect the dependent variable

When participants guess the research hypothesis, to eliminate this cover stories, unrelated experiments, and nonreactive measures can be used

The experimenter may treat subjects differently because they know what condition they’re in, to avoid this naive or blind experimenters can be used

The extent to which results can be generalized outside the experimental conditions

The extent to which the research is conducted in situations that are similar to everyday life

When a study creates the hoped-for changes

Repeating the experiment exactly how it was previously done

Comparing a new population to the original population

Testing the same conceptual variable, but with a different operational definition

Adding new conditions to an experiment to rule out alternative explanations

Cannot be sure that the program and the control group are equivalent

Unable to control for all threats to internal validity

All of the above

Changes in the research participants over time

People who stay with the program may be different than those who drop out

Changes in the social climate over time

Measuring changes in a single person

Grouping based on preexisting characteristics (e.g sex)

The dependent variable is assessed regularly both before and after the intervention
