Measurement
Nominal, Ordinal, Interval, Ratio
What are the Scales of Measurement?
Dependability, reproducibility, stability, and consistency are all characteristics, or rather synonyms, of what measurement characteristic.
What is reliability?
This type of reliability measures consistency over time.
What is Test-Retest reliability?
This is the extent to which meaningful and appropriate inferences can be made from an instrument?
What is validity?
What is face validity?
Gender, Race, Presence or Absence of Diagnostic criterion are all types of this measurement scale
What is Nominal Scale
This is the bias, or "radio static," in an observed score.
What is measurement error?
This type of reliability measures consistency of scores of individuals within the same group on two alternate but equivalent forms of the same test.
What is Alternate-Forms Reliability?
Three darts thrown at a dart board in which all three darts hit the bullseye is a great representation of a high score on what measurement construct?
What is reliability AND validity?
Content validity measures if individual questions on a test are representative of this.
What is the domain or construct of interest
This form of measurement scale has magnitude but does not have equal interval
Pearson product-moment correlation coefficient, commonly denoted as "r", is the most common measurement of this statistical construct.
What is correlation?
Split-half reliability and inter-item consistency are two measure of this type of reliability.
What is Internal Consistency?
Three darts thrown on a dart board no where close to one another is a great representation of a low score on what measurement construct?
What is reliability AND validity?
This form of validity is measured when you compare test scores from one test to performance on another test that measures the same construct.
What is Criterion-Related Validity?
This form measurement scale has magnitude, equal interval, but no absolute zero.
What is Interval Scale
All correlation/reliability coefficients fall in this value range.
What is +1 to -1?
This is the most common way to divide a test into comparable halves for split-half reliability?
What is odd and evens?
Three darts thrown at a dart borad right next to each other in the double 17 section is a great representation of a high score on what measurement construct?
What is reliability?
This type of validity measures teh degree to which an assessment is related to a theoretical construct (convergent) or not (discriminant).
What is construct validity?
What is magnitude, equal interval, and absolute zero.
Reliability estimate expresses the relationship between the true score and this other score.
What is the observed score?
This form of reliability is calculated by dividing the number of agreements by the number of possible agreements (or total number of items).
What is Interrater Reliability?
________ without ___________ is possible, where the inverse is NOT possible.
These are different actions conducted by the client while taking a test that may lead to low validity scores.
What is Clients pretending to have some problem, clients responding randomly, or responding in a socially desirable way?
