Experiments
This is when the cause variable comes before the effect variable.
What is temporal precedence?
This type of design includes a set of measurements taken at intervals over a period of time.
What is the interrupted time series design?
This form of reliability is when you administer the same measure again after a period of time
What is Test -Retest Reliability?
This type of validity assesses how well were the variables measured and manipulated
What is Construct validity?
Things (ex. external evensts) that might have happened between the pretest and the posttest that caused a change from pretest to posttest
What is history
These are the two hallmarks of a true experiment
What is manipulated and random assignments?
This is a between-subjects design in which participants have not been randomly assigned to conditions.
What is nonequivalent groups design?
This form of reliability is when you get consistent scores no matter who does the measuring
What is interrater reliability?
The ability to generalize results to other individuals or settings
What is external validity?
Participants might have changed between the pretest and the posttest in ways that they were going to anyway because they are growing and learning.
What is maturation
This is always a measured, outcome variable
What is an dependent variable?
This type of design is when nonequivalent groups are administered a pretest of the dependent variable, then one group receives a treatment while a nonequivalent control group does not receive a treatment, the dependent variable is assessed again, and then the treatment is added to the control group, and finally the dependent variable is assessed one last time.
What is the pretest-posttest design with switching replication designdesign?
If Validity = Truthfulness of the measure, Reliability =
What is Consistency?
This is when a measure appears to be valid on the surface
What is face validity?
Basic characteristics of the measuring instrument change over time.
What is a instrumentation?
In a true experiment this is always manipulated
What is the independent variable?
This design is when there is a treatment group that is given a pretest, receives a treatment, and then is given a posttest. But at the same time there is a nonequivalent control group that is given a pretest, does not receive the treatment, and then is given a posttest.
What is pretest-posttest nonequivalent groups design?
A measure can be reliable but not
What is Valid?
This assesses how well do the data support the causal claim
What is Statistical validity?
The statistical fact that an individual who scores extremely high or extremely low on a variable on one occasion will tend to score less extremely on the next occasion
What is the regression to the mean?
When the control group is exposed to an inert treatment
What is the placebo group?
In this kind of design includes participants in one group are exposed to a treatment, a nonequivalent group is not exposed to the treatment, and then the two groups are compared.
What is a posttest only non-equivalent group design?
A participant provides a consistent pattern of responses, regardless of how the researcher has phrased the question
What is internal reliability?
This type of validity assesses how well a new measure correlates with previous measures.
What is establishing convergent validity?
Due to subject loss (attrition), the group equivalence formed at the start of the study may be destroyed
What is subject attrition?
