Researchers consistently fail to report reliability estimates for data used in their studies. This lack of reporting hinders appropriate evaluation and interpretation of data and may lead to inappropriate conclusions. Because reliability is inured to scores obtained from a test, and not the test itself, it is important to report score reliability…

Effects of Some Variations in Rating Scale Characteristics on the Means and Reliabilities of Ratings
Peer reviewedFinn, R. H. – Educational and Psychological Measurement, 1972
Since both the means and reliabilities of the ratings were affected by the number of scale levels but not by the manner of defining scale levels, it would appear that the most critical consideration in rating scale construction is that of determining the appropriate number of rating scale levels.

Bitter, James A. – Meas Evaluation Guidance, 1970
Results suggest that: (1) the Work Adjustment Rating Form (WARF) is subject to rater bias that can significantly affect the scale's predictive validity for individual raters; (2) rater bias did not affect the mean predictive validity and the mean reliability estimate; and (3) rater bias can be minimized by using more than one rater.

Peer reviewedMayer, John D. – Perceptual and Motor Skills, 1983
Kelly's formula estimates sampling variance of correlation corrected for attenuation by using split-half reliabilities. In some cases, coefficient alpha estimate of reliability is preferable. A simulation study suggests a variation of Kelly's formula can be used appropriately with coefficient alpha. Kelly's formula is modified to accept…

Peer reviewedSinclair, Keith – Journalism Quarterly, 1982
Analyzes press coverage of the 1979 British general election to determine if reporting concentrated on the "dramatic contest" aspects of the campaign or on issues. Concludes that while coverage of the "dramatic contest" aspects of the election increased as the campaign went on coverage of the issues remained the major focus.…
