measurement in selection and reliability Flashcards
(33 cards)
two types of variables must be identified for _:
- _ (what is meant by employee success on the job), e.g. _ ratings of work performance
- _ (measures of WRCs identified through job _)
prediction, criterion, supervisory, predictor, analysis
_ scale: two or more mutually exclusive categories
nominal
_ scale: rank-order objects of individuals from high to low
ordinal
_: uses constant units of measurement to rank-order
interval
_ (2): has an absolute zero point, and differences between numerical values have meaning
ratio scale
a predictor or criterion is _ if:
- same _
- administration: information is _ in the same way
- rules for _ exist
standardized, content, collected, scoring
predictor or selection procedures e.gs: _ information, interviews, _
background, tests
advantages of using existing measures:
- _ expensive
- less _
- have an idea of _ and _
less, time-consuming, reliability, validity
norm _: establishing a person’s _ position _ a group of others
referencing, relative, against
to interpret the results of measurement, we need to know:
- _ (3) on the selection procedure
- the _ of the selection procedure
how others scored, validity
characteristics of a normal distribution:
- _ shaped
- _ to either side of the _
- mean score is the _ point on the curve
- mean is the _ between min and max
bell, symmetrical, mean, highest, mid-point
_ scores show the percentage of persons in a norm group who fall _ a given score on a measure
percentile, below
the _ the percentile score, the _ a person’s performance _ to others
higher, better, relative
_ scores represent _ to raw scores
standard, adjustments
_ scores are a form of standard score
stanine
_ (3), also called modern psychometrics, is another alternative to classical test theory
item response theory
The basic idea underlying item response theory is that an individual’s _ on a test item is determined by:
- the individual’s _ (2) on the attribute being assessed
- the _ associated with the item
response, trait level, qualities
each item on an item response test has its own item “_ (2)”
characteristic curve
with item response theory, _ can be measured on a _ scale
ability, standardized
in a _ item characteristic curve, as soon as the ability of the respondent _ the difficulty of the question, the probability of a _ answer rises instantly from _ to 100%
perfect, meets, correct, 0
item _ is a “location index”
difficulty
item _ describes how well an item can identify _ in the respondent’s ability
discrimination, differences
item banks are a _ of test questions, ensures increased test _ as different test takers receive _ items
repository, security, different
classical test theory and item response theory are item _ methods
scoring
