Guide: Measurement, Validity, Recruitment,
and Performance Management Questions
and Answers Exam
What is measurement? - ANSWER>>Assigning numerals to objects or events
according to rules.
What is a trait? - ANSWER>>A descriptive label applied to a group of interrelated
behaviors that may be inherited or acquired.
What is the lowest level of measurement? - ANSWER>>Nominal scale.
What does the nominal scale represent? - ANSWER>>Differences in kind, used
only to classify/categorize.
What is the main operation of the nominal scale? - ANSWER>>Equality (A = B or A
≠ B).
What is an example of a nominal scale? - ANSWER>>Male/female coded 0/1.
What does the ordinal scale classify? - ANSWER>>By category and gives an
indication of magnitude.
What is transitivity in the ordinal scale? - ANSWER>>If A > B and B > C, then A > C.
, What statistics are used with ordinal scales? - ANSWER>>Median, percentile
ranks, rank-order correlations, rank-order ANOVA.
What is the key feature of the interval scale? - ANSWER>>Differences between

What is reliability? - ANSWER>>Freedom from unsystematic errors of

What is test-retest reliability? - ANSWER>>Same test, same group, on two
different occasions.
What is parallel/alternate forms reliability? - ANSWER>>Checks consistency across
different but similar forms of a test.
What does internal consistency measure? - ANSWER>>How well the items on a
test hang together.
What is interrater reliability? - ANSWER>>Used when multiple raters are judging
