100
This is a method of gathering information; testing and interviewing are forms of this
What is Assessment?
100
The major category of validity indicates that the measure contains representative content
What is Content Validity?
100
This is the correlation coefficient above which testers can be assured that the measure is reliable
What is .80?
100
A correlation of .13 between two variables indicates WHAT about the direction and WHAT about the strength of the relationship
What is positive and weak (or low/small)?
100
This is one thing that is unique about the bell or normal curve
What is that it is completely symmetrical (or proportioned) or Mean, Median, Mode are identical?
200
The very first psychological test was invented to measure this
What is IQ or intelligence?
200
The occurs when a test predicts variable which it should
What is Predictive Validity?
200
It has to do with the consistency between two raters
What is Inter(Between)-rater Reliability?
200
This is a way of presenting data by indicating the frequency of responses at specific levels
What is Frequency Distribution?
200
This is a reference group used for comparison of a tested individual to a sample of his or her peers
What is a Normative Sample (or Norm)?
300
An effect that can be seen when a test is too hard
What is a floor effect?
300
This occurs when two tests based on the same construct given at the same time agree
What is Concurrent Validity?
300
This form of reliability measures the consistency between the test scores taken at two separate times
What is Test-Retest Reliability?
300
THESE refer to two ways to measure central tendency and THESE refer to two ways to measure variability
What are Mean, Median Mode and Range, Variance, Standard Deviation?
300
A person's observed ability is composed of these three components
What are true ability, random error, and systematic error?
400
An effect that can be seen when a test is too easy?
What is a ceiling effect?
400
This occurs when a test does not correlate with another test which measures a different construct
What is Discriminant Validity?
400
This form of reliability looks for consistency between two different versions of the same test
What is Parallell (Alternate) Forms Reliability?
400
These are classifications of data: The first refers to categories, the second refers to ordered categories, the third refers to a number with equal spacing between numbers and the last refers to a true number with an absolute zero.
What is Nominal, Ordinal, Interval, Ratio?
400
These are two ways to reduce error
What are... Pilot Test, Follow Directions, Double-Check, Use Statistical Procedures, Use Multiple Measures, Be Careful with Extrapolation
500
These are two of our ethical and legal obligations to clients during testing
Confidentiality, Consent, Least stigmatizing label, Test is given in native language, Understanding ethnicity guidelines, Administrator must be trained
500
This occurs when two tests based on different but related (similar) constructs correlate
What is Convergent Validity?
500
This type of reliability measures internal consistency between the two halves of a measure
What is Split Half Reliability?
500
This first statistical analysis is used in testing to identify subtests whereas the second statistical technique is used to make a specific prediction of a score based upon a correlation
What is Factor Analysis and Regression?
500
These are two ways in which tests are commonly misused
What are... Taking a test Title Literally, Ignoring Measurement Error, Use of a Single Test for a Decision, Reporting Incorrectly, Assigning Causation
