What are sources of validity evidence?
The American Psychological and Education Research Associations published standards that identify 5 sources of validity evidence: (1) Content, (2) Response Process, (3) Internal Structure, (4) Relation to Other Variables, and (5) Consequences 26(see Table 1) Notably, this 5-category validity framework, articulated by …
What is the relationship between validity and reliability?
Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
What is the difference between criterion validity and content validity?
There are four main types of validity: Construct validity: Does the test measure the concept that it’s intended to measure? Content validity: Is the test fully representative of what it aims to measure? Criterion validity: Do the results correspond to a different test of the same thing?
What is discriminant validity example?
Discriminant validity tests whether believed unrelated constructs are, in fact, unrelated. Discriminant validity would ensure that, in the study, the non-overlapping factors do not overlap. For example, self esteem and intelligence should not relate (too much) in most research projects.
What is the difference between convergent and discriminant validity?
What are Convergent Validity and Discriminant Validity? Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. Conversely, discriminant validity shows that two measures that are not supposed to be related are in fact, unrelated.
Which is an example of convergent validity?
For example, in order to test the convergent validity of a measure of self-esteem, a researcher may want to show that measures of similar constructs, such as self-worth, confidence, social skills, and self-appraisal are also related to self-esteem, whereas non-overlapping factors, such as intelligence, should not …
Why is convergent validity important?
What is convergent validity? Convergent validity helps to establish construct validity when you use two different measurement procedures and research methods (e.g., participant observation and a survey) in your dissertation to collect data about a construct (e.g., anger, depression, motivation, task performance).
How do you conduct convergent validity?
To establish convergent validity, you need to show that measures that should be related are in reality related. In the figure below, we see four measures (each is an item on a scale) that all purport to reflect the construct of self esteem.
Why validity implies reliability but not the reverse?
The reliability refers to the phenomenon that the measurement instrument provides consistent results. A valid measurement is always a reliable measurement too, but the reverse does not hold: if an instrument provides consistent result, it is reliable, but does not have to be valid.
What is meant by the statement Reliability is a necessary condition for validity?
What is meant by the statement “reliability is a necessary condition for validity”? Test scores that are valid have a significant degree of reliability. You just studied 11 terms!
Which statement best shows the relationship between placement and selection?
Which statement best shows the relationship between placement and selection? Placement is synonymous with selection. Placement does not involve rejection, but selection does. Placement involves exclusion of some students from the institution while selection does not.
How can a teacher attain a high level of consistency in scoring his/her assessment tasks?
How can a teacher attain a high level of consistency in scoring his/her assessment tasks? Prepare and use scoring rubrics. content-related evidence. Spelling test results that are valid for ranking students in spelling contests are likely to be equally valid for evaluating the types of word patterns students can spell.
