MODULE 1 AND 2 QUIZ QUESTIONS

This type of reliability is used to assess whether or not a testing instrument is capable of measuring a variable with consistency. - Answer - Test-retest reliability What is the range in which a reliability coefficient can fall between? - Answer - 0.00 through 1.00 What happens when a reliability ratio falls closer to zero? - Answer - It becomes less reliable Two experimental groups of adults have completed a questionnaire producing an average score of 50. The first group had scores above 60 and the other had scores below 40. When discussing the phenomenon of regression toward the mean, which would be likely prediction to occur as these same two experimental groups take a retest? - Answer - The group average moves closer to 50 The following are all characteristics describing systematic errors except: - Answer - Primarily a concern for reliability Which is not one of the components of the measurement system that measurement error can be attributed to? - Answer - Number of trials What is the reliability coefficient used when analyzing the internal consistency of a questionnaire? - Answer - Cronbach's coefficient alpha Which of the following is the best way to assess INTER-RATER reliability? - Answer - Having all of the raters simultaneously watch a video of a patient performing measurable activities A manual muscle test on a patient with shoulder pain is experienced differently by a patient with a limited range of motion, so these results cannot automatically be attributed to one another. This is an example of what concept in generalizability? - Answer - Population-Specific reliability This type of reliability is used when there is a possibility that the participants are able to recall their responses from initial test items. - Answer - Alternate forms reliability Clinical trials ca
