NURS 329 FINAL ASSESSMENT 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◉ Operational definition. Answer: The researcher must specify the
objective criteria and how they're measuring the variables.
◉ Measurement error. Answer: Refers to how well or how poorly a
particular instrument performs in a given population.
◉ Random error. Answer: Chance factors that contribute to
measurement error.
◉ Systematic error. Answer: Error arising from the instrument itself, the
process, or the participant.
◉ Formula for measurement error. Answer: Obtained score = true score
+/- error of measurement.
◉ Levels of measurement. Answer: Nominal, ordinal, interval, and ratio
are the four levels of measurement.
,◉ Nominal level. Answer: Lowest level of measurement; classifies
study participants into two or more categories, each with 'equal' value.
◉ Dichotomous nominal. Answer: Nominal measurement with two
options; yes/no.
◉ Ordinal level. Answer: Categories that specify the order of items
being measured (rank) but do not specify how far apart they are.
◉ Interval level. Answer: Possesses characteristics of nominal and
ordinal levels plus equal interval size, but no true zero point.
◉ Ratio level. Answer: Highest level of measurement; ordered and
separated by a constant unit of measurement with an absolute zero.
◉ Continuous variable. Answer: A variable that takes on an infinite
number of different values presented on a continuum.
◉ Instruments in research. Answer: Tools used to measure variables in
research.
◉ Reliability. Answer: Consistency with which an instrument or test
measures what it is supposed to measure.
, ◉ Types of reliability. Answer: Refers to the extent to which a
participant's performance remains consistent across repeated testing.
◉ Examples of nominal variables. Answer: Gender, education, marital
status, religion, diagnosis.
◉ Examples of ordinal variables. Answer: Military rank, household
income.
◉ Examples of interval variables. Answer: Temperature, knowledge
tests.
◉ Examples of ratio variables. Answer: Height, weight, age.
◉ Test‐retest. Answer: Same instrument, same people, two times
◉ Minimum for Test‐retest. Answer: Minimum of 0.75
◉ Internal consistency/Cronbach's alpha. Answer: Homogeneity
(internal agreement among items measuring concept)
◉ Minimum for new instrument (Internal consistency). Answer:
Minimum of 0.70 for new instrument
