Running head: SOURCES OF TEST ERRORSource of Test ErrorName of StudentUniversity Affiliation1SOURCES OF TEST ERROR2Source of Test ErrorReliability is measured by conducting two same experiments with the instrument; if theresults are the same, then the results are reliable; if the results are not the same, an error hasoccurred. The lack of consistency shows is a pointer to the existence of errors when carrying outtests.The common sources of error entailThe InstrumentThe instrument which is used to carry out tests may be a source of error. This happens when aninstrument is faulty or misbehaves when conducting the second test. It is possible for athermometer to function normally when conducting the first test, but misbehave whenperforming the second test.Systematic BiasThese are errors that occur in measurements and are always predicable because they occur inspecific ways (Miller, & Robert, 2020). For example, when measuring the temperature of apatient, systematic bias occurs when a second measurement leads to underestimating thetemperature reading. This happens when measuring the temperatures of various patients.Assessor ErrorsLinked to the placement of ...
