The phrase "a coefficient of reliability" is correct and usable in written English.
It can be used in contexts related to statistics, research, or measurement where reliability is being quantified.
Example: "The study reported a coefficient of reliability of 0.85, indicating a high level of consistency in the results."
Alternatives: "a reliability index" or "a reliability coefficient".
Cronbach's alpha is a coefficient of reliability (or consistency).
Krippendorff's Alpha was a coefficient of reliability developed by Krippendorff (2004).
c-alpha is not a statistical test, but a coefficient of reliability based on the correlation between individual indicators.
Retest reliability was measured in two ways, using a coefficient of reliability and units of measurement (kilograms).
Internal consistency was assessed using Cronbach's alpha, a coefficient of reliability that indicates how closely related a set of items are to one another.
Finally, Cronbach's alpha, a coefficient of reliability was used as a measure of the level of consistency of opinion among the respondents for each theme in the second round of the questionnaire.
Ayral et al. [ 1] reported a poor coefficient of reliability (0.27 0.73) based on a review of the grading of cartilage lesions made by nine surgeons.
The six items retained in the analysis (outlined in italic font) provided a satisfactory coefficient of reliability: Kuder Richardson (KR20) = 0.63 [ 26].
Within a two-week period, the mesiodistal widths of 10 pairs of casts were re-measured by the same investigator, and a high coefficient of reliability was observed (r = 0.936).
The following equation allowed estimation of the reliability coefficient of the mean (Rk) by averaging k trials with a 1-measure reliability coefficient R: We also estimated the number of trials (k) averaged to obtain a target coefficient of reliability (R*) with the following formula: The number of trials (k) needed to obtain an average-measure ICC of at least.80 was calculated.
Most marginal reliability estimates were 0.80 or higher, with higher reliability approaching a coefficient of 1, suggesting good reliability at the area of reliability relevant to screening.
