Reliability
The extent to which repeated measurements yield consistent results.
What is Reliability?
A measurement that measures what it is supposed to assess.
What is Validity?
Your program did not create the outcome, but an event occurred.
What is historical threat?
The documented value is different than the true value.
What is measurement error?
The term generalization refers to this.
What is external validity?
Determined from measurements of the same subjects on two occasions.
What is retest reliability?
Refers to the approximate truth of conclusions that involve generalizations.
What is external validity?
It is not your program producing results, but normal development is occurring.
What is maturation threat?
These errors are a matter of chance.
What is random error?
The test itself creates a change in the observed variable.
What is testing effect?
What is the stability of data recorded by one tester across two or more trials?
What is Intra-Rater reliability?
Proximate truth about inferences regarding cause-effect or causal relationships.
What is internal validity?
This threat has the motto "you can only go up from here."
What is regression threat?
Predictable errors of measurement.
What is systematic error?
This relative reliability coefficient provides the most reliable sample.
What is 1.0?
Variation between two or more raters who measure the same subjects.
What is Inter-Rater Reliability?
An example of this is all of darts spread across the board with no misses.
What is high validity-low reliability?
An example of this threat is when examinees are dropping out of tests due to the chance of a perceived low score.
What is mortality?
An example of this error is the teacher is inattentive during testing.
What is random error?
The statistic most often used for internal consistency.
What is Cronbach’s coefficient alpha?
Combining two sets of items and creating content into one longer instrument.
What is Split-Half Reliability?
When all the darts hit the bullseye.
What is high reliability-high validity?
A group gets treatment over a comparable group. The other group puts pressure on the administration for treatment.
What is compensatory equalization of treatment?
Measuring natural fluctuations in a person's weight is an example of.
What is a random error?
The amount of change in a variable that must be achieved before we can be confident that error does not account for the entire measured difference.
What is minimal detectable change?
