Chapter 5.1 Nature of Test Flashcards
Aside from considering the sources of error from test construction, test administration, or scoring and interpretation, one must also consider the______in measuring their reliability
nature of the test
This focus if the test measures one trait or multiple triats
Homogeneity VS Heterogeneity of test items
______will yield high inter-item consistency while heterogenous will yield lower-inter item consistency
Homogenous test ;
Anong gagawin to measure the reliability of heterogenous items?
Mas maganda per subscale ang pag measure kapag heterogenous
This focuses if the test measure a characteristic that is stable over time or something that is shifting from time to time
DYNAMIC VS Static Characteristics
What reliability estimates we can use in static characteristics/personality traits?
lahat ng reliability estimates
What reliability estimates we can use in dynamic characteristics/states
internal consistency while test-retest is not allowed
This focuses if the variance of either variable in a correlational analysis is restricted by the sampling procedure used
RESTRICTION OR INFLATION OF RANGE
In restriction or inflation of range, if the sample size is low then the correlation is___
lower
If the variance of either variable in a correlational analysis is inflated by the sampling procedure, then the resulting correlation coefficient tends to be _______
higher
It focuses on the number of items
Number of items
________it favors higher items
Cronbach’s alpha
In _________ time limit is long enough to allow test takers to attempt all items, and if some items are so difficult that no testtaker is able to obtain a perfect score
Power Test
In _______ it contains items of uniform level of difficulty (typically uniformly low) so that, when given generous time limits, all test takersers should be able to complete all the test itecorrectly.
Speed Test
Example of power test
intelligence test
