When calculating correlations, the most common method used is the:A : Pearson-Product Moment Correlation Coefficient.B : Correlation Coefficient of Most Common Factors.C : Reliability Coefficient of Correlation.D : Reliability Correlation Coefficient.
Which of the following is NOT one of the assumptions that should be met when establishing the reliability of an instrument using the test-retest method?A : Test-retest reliability is only valid when measuring situational traitsB : The characteristic or trait measured should be stable over timeC : There should be no differential in practice effectD : There should be no differential in learning between the test and retest
The Spearman-Brown formula is used:A : to correct a test-retest reliability coefficient.B : to correct a split-half reliability coefficient.C : when the items are all of the same difficulty level.D : when the items are of differing levels of difficulty.
The most significant difficulty with estimating reliability with the alternate or parallel forms procedure isA : calculating the correlation coefficient using two different forms.B : the effects of remembering specific items in the second testing.C : developing two sound instruments that are equivalent or parallel.D : finding two similar sets of test takers.
For which of the following tests would a test-retest reliability estimate be least appropriate?A : Intelligence testsB : Tests of moment-to-moment mood changesC : Academic achievement testsD : Instruments to measure art aptitude
Correlation coefficients range from:A : -1.0 to 1.0.B : 0 to 1.0.C : 0 to -1.0.D : -5.0 to 5.0.
With a reliability coefficient of .81, using classical test theory we would interpret that the:A : amount of error variance to observed variance is 81 percent.B : amount of true variance to observed variance is 81 percent.C : instrument has good enough reliability.D : instruments validity coefficient would be 0.812.
Systematic error (as compared to unsystematic error):A : significantly lowers the reliability of an instrument.B : insignificantly lowers the reliability of an instrument.C : increases the reliability of an instrument.D : has no effect on the reliability of an instrument.
What statistical technique is often used to calculate an estimate of reliability?A : RegressionB : Analysis of varianceC : Factor analysisD : Correlation
If we interpreted a reliability coefficient to indicate that 80% of the variance was true variance to observed variance, what would be the ratio of error variance to observed variance?A : 0.20B : 0.40C : 0.60D : 0.80
The statistic that represents the percentage of shared variance between two variables is the:A : correlation coefficient.B : reliability correlation.C : coefficient of determination.D : coefficient of shared variance.
According to classical test theory, if the observed variance of a test is 50 and the true variance is 40, what is the estimated reliability of the test?A : 0.40B : 0.50C : 0.80D : 0.90
A correlation coefficient is an indicator of:A : the validity of an assessment.B : the variability of the obtained scores.C : the relationship between two sets of data.D : the fluctuation of an individuals score over time.
