Geographically Weighted Cronbach's Alpha
, 2023 As individual’s cognitions and behaviours are affected by where they live, the reliability of responses to tests or scales may vary with location. In this paper, we develop a local version of Cronbach’s alpha, geographically weighted Cronbach's alpha, to investigate how the reliability of the measure varies spatially.

Clarity on Cronbach’s Alpha Use [PDF]
Journal of Chemical Education, 2020 The Cronbach’s alpha (α) statistic is regularly reported in science education studies. However, recent reviews have noted that it is not well-understood. Therefore, this commentary provides additional clarity regarding the language used when describing and interpreting alpha and other estimates of reliability.

An aberrant abundance of Cronbach's alpha values at .70
Advances in Methods and Practices in Psychological ScienceCronbach’s α is the most widely reported metric of the reliability of psychological measures. Decisions about an observed α’s adequacy are often made using rule-of-thumb thresholds, such as α of at least .70.

Cronbach’s Alpha: Genesis, Issues and Alternatives
IMIB Journal of Innovation and ManagementThe most widely used metric for assessing a scale’s reliability is Cronbach’s alpha. Since its introduction in 1951 by Lee Cronbach, it has evolved into the accepted benchmark for scale reliability. A quick search for ‘Cronbach’s alpha’ in Google Scholar yields more than 8 hundred thousand results.

Confidence Intervals for Cronbach's Coefficient Alpha Values [PDF]
, 2003 Coefficient Alpha, which is widely used in empirical research, estimates the reliability of a test consisting of parallel items. In practice it is difficult to compare values of alpha across studies as it depends on the number of items used. In this paper we provide a simple solution, which amounts to computing the confidence intervals of an alpha, as ...
