Validity Flashcards
It refers to the degree to which the measurement procedures measure the variable that it claims to measure
Validity
what/give the aspects of validity
face validity
contentc validity
criterion validity
construct validity
is the simplest and least scientific form of validity and it is demonstrated when the face value or superficial appearance of a measurement measures what it is supposed to measure
face validity
this type of validity is concerned with the extent to which the test is representative of a defined body of content consisting of topics and processess
content validity
two types of construct validity
construct underrepresentation
construct-irrelevant variance
failure to capture important components of a construct
construct underrepresentation
happens when scores are influenced by factors irrelevant to the construct
construct-irrelevant variance
formula of content validity ratio
CVR= n-(N/2) / N/2
who developed the formula content of validity ratio?
Lawshe
Identify if good or bad Validity
An IQ test containing items which measure memory, mathematical ability, verbal reasoning and abstract reasoning
good Face Validity
identify whether good or bad face validity
an Iq test contaning items which measures depression and anxiety
bad face validity
true or false
content validity is done by statistical analysis not by the inspection of items
false. conntent validity is NOT done by statistical analysis BUT by the inspection of items
involves the relationship or correlation between the tests scores and scores on some measurement representing an identical criterion
Criterion Validity
types of criterion validity
predictive validity
concurrent validity
true or false
correlation coefficient can be computed between the acores on the test being validated and the scores on criterion
true
it is demonstrated when scores obtained from a measure accurately predict behavior according to theory
predictive validity
it is established when the scores of a measure (predictor) is correlated with the scores of a different measure (criterion) taken at the same time
concurrent validity
college entrance test predict whether a student can meet the demand and standards of a college or university is an example of what validity
kapag specific : predictive validity
kapag general term:criterion validity
a test which measures learning disabilities should be significantly and negatively correlated with a test measuring school performance is an example of what validity
specific: concurrent
general:criterion
a test measure anger is expected to be significantly and positively correlated with a test measuring violent and aggresive behvaior is an example of what validity
specific: concurrent
general: criterion
