Kr 20 reliability coefficient interpretation

WebCronbach's alpha (Cronbach's ), also known as rho-equivalent reliability or coefficient alpha (coefficient ), is a reliability coefficient and measure of internal consistency of tests and measures.

Web15 jan. 2024 · KR-20 is used to measure the reliability of tests in a dichotomous item (17). Therefore, in this study, KR- 20 was used to estimate the test reliability. The objective test items were scored dichotomously as right or wrong (17). Every correct response was coded as 1 and wrong responses as 0. The acceptable value for test reliability in many ... The name of this formula stems from the fact that is the twentieth formula discussed in Kuder and Richardson's seminal paper on test reliability. It is a special case of Cronbach's α, computed for dichotomous scores. It is often claimed that a high KR-20 coefficient (e.g., > 0.90) indicates a homogeneous test. However, like Cronbach's α, homogeneity (that is, unidimensionality) is actually an assumption, not a conclusion, of reliabilit…
