Psych320 Final Exam Chapter 1-6
Terms in this set (39)
The use of tests and other tools of evaluation.
An advantage of using a panel interview format is that
The effects of the biases of individual interviewers are minimized.
A clinician administers a computerized psychological test in her own office. Minutes after the examinee has completed the test, the same computer used to administer the test now spews out a report of the findings from that test. This is an example of
Scale used for categorical data
Certain amount of space in between
Used to come up with proportions
Which is the only type of scale that has an absolute zero point?
Ratio (true zero)
Yards gained by running backs during a football game is an example of which type of scale
A frequency distribution typically includes
Each possible score and how often it occurs.
What is the variance in a score?
Standard deviation squared
A z score scale has sometimes been referred to as a "zero plus or minus one" scale because a z score scale
Has a mean set at 0 and a standard deviation set at 1.
If the results of an examination are positively skewed, the exam questions were likely
If few scores fall on the negative side of the distribution, the distribution is ________ skewed.
It is correct to conceive of error "creeping into" the measurement process because
Error is a well acknowledged part of the measurement process.
The term psychometric soundness is typically a reference to a test's reliability and
Norm-referenced testing and assessment is both a method of evaluation and a way of deriving meaning from tests scores. Individual testtaker scores are evaluated against
The scores of a comparison group of test takers.
How do states different from traits
A trait is relatively enduring, whereas a state is relatively short-lived.
When measuring a particular psychological trait, the term error variance refers to
The component of a test score attributable to sources other than the trait
The term norms refers to
Scores with which the results of measurement can be compared.
A test is said to be standardized if the test's manual contains clearly specified procedures for test
Administration, Scoring, and Interpretation
The more homogeneous a test is, the
More inter-item consistency it can be expected to have.
One of the problems associated with classical test theory has to do with
Its assumptions concerning the equivalence of all items on a test.
Classical Test Theory
A body of related psychometric theory that predicts outcomes of psychological testing such as the difficulty of items or the ability of test-takers. ... Generally speaking, the aim is to understand and improve the reliability of psychological tests.
Item Response Theory
Example: GRE, keeps giving you more difficult questions, it doesn't make the assumption, weighted questions and adaptive tests
A confidence interval is a range or band of test scores that
is likely to contain the true score.
The standard error of measurement
is used to infer how far an observed score is from the true score.
Also known as the standard error of a score.
Is used in the context of classical test theory.
^^All of these
Which type of reliability estimate would be appropriate only when evaluating the reliability of a test that measures a trait that is presumed to be relatively stable time
An estimate of test-retest reliability is often referred to as a coefficient of stability when the time interval between the test and retest is more than
Which of the following is usually minimized when using split-half estimates of reliability as compared with test-retest or parallel/alternate-form estimates of reliability
Time and expense
Test-retest estimates of reliability are referred to as measures of ________, and split-half reliability estimates are referred to as measures of ________.
Stability; internal consistency
It's a measure of validity that arrived at by a comprehensive analysis of how scores on the test relate to other test scores." This statement is a reference to:
The extent to which the test measures the theoretical trait (convergent and discriminant) Are you measuring what you mean to be measuring? EX: how do these scores on the test relate to other test scores
Test includes all areas of interest, to what extent does it measure what is expected
The extent to which a measure is related to an outcome
Correlation between the test and behavior (outcome) on how you want to make inferences. Is the thing you are measuring correlating with what you are expecting to find? Is it related? (Has concurrent and predicative)
Refers to a comparison between the measure in question and an outcome assessed at the same time.
"Is this concept fitting in logically where we want it to"
Are they getting the same thing both times?
Is it predicting what you would expect (scoring high on adaptive performance...would it expect to predict performing well in a workplace"
The degree to which an additional predictor explains something about the criterion measure that is not explained by predictors already in use.
The criterion measure is influenced by the predictor measure.
