Anything Goes
100
Psychometric property that indicates low measurement error and repeatable results.
What is reliability?
100
Inferential test used to compare experimental conditions in a single-factor, two-level matched groups or repeated measures design.
What is a t-test for related samples?
100
Used to describe research designs when there is more than one independent variable within the design.
What is a factorial design?
100
Changes in the dependent variable are due to normal growth and development.
What is maturation?
100
The process of reasoning from the results of many experiments to a generalized theory.
What is induction?
200
A measurement scale in which data is divided into mutually exclusive categories which have an associated order.
What is an ordinal scale?
200
Inferential test used to compare experimental conditions in a single-factor, two-level independent groups design.
What is a t-test for independent samples?
200
A procedure used to control for sequence effects.
What is counterbalancing?
200
When groups in study are differentially affected by an outside event.
What is history?
200
A problem that bias results in cross-sectional studies when groups are bonded by time or common life experiences.
What is a cohort effect?
300
A measurement scale which has a true zero and allows for all math computations.
What is a ratio scale?
300
Considered to be a better measure of central tendency when outliers are present.
What is the median?
300
Used to spread possible confounds throughout groups within the study.
What is random assignment?
300
Refers to the adequacy of operational definitions.
What is construct validity?
300
When the fffect of one IV depends on the level of another IV.
What is an interaction effect?
400
Does not allow for distinction in high scores.
What is ceiling effect?
400
Rejecting the null when it is really true.
What is a Type I error?
400
Designs with more than two groups that enable the researcher to detect non-linear effects.
What are multi-level designs?
400
The extent to which results are applicable to everyday life.
What is ecological validity?
400
A subject trait that is measurable and is thought to be highly correlated with the DV.
What is a matching variable?
500
Does not allow for distinction in low scores.
What is floor effect?
500
Retaining the null when it is really false.
What is a Type II error?
500
The type of design that has two IV’s, each with two levels.
What is a 2 X 2 factorial design?
500
The extent to which statistical tests are properly used and appropriate conclusions are drawn from statistical analysis.
What is statistical conclusion validity?
500
An uncontrolled extraneous variable that “covaries” with the IV and could provide an alternative explanation of the results.
What is a confound?
