The rating reliability calculator
BACKGROUND Rating scales form an important means of gathering evaluation data. Since important decisions are often based on these evaluations, determining the reliability of rating data can be critical. Most commonly used methods of estimating reliability require a complete set of ratings i.e. every subject being rated must be rated by each judge. Over fifty years ago Ebel described an algorith...
متن کاملLoad Rating versus Reliability Analysis
The most common approach to assess the safety of a bridge is load rating. However, this approach cannot quantify the bridge safety in probabilistic terms or fully quantify the structural risk to the bridge. Reliability methods have become an increasingly popular and gradually accepted approach to assess the safety of structures. These methods account for the randomness and correlation of all re...
متن کاملReliability Analysis of Core Protection Calculator System using Petri Net
As digital systems are introduced to nuclear power plants, issues related with reliability analyses of these digital systems are being raised. One of these issues is that static Fault Tree (FT) and Event Tree (ET) approach cannot properly account for dynamic interactions in the digital systems, such as multiple top events, logic loops and time delay. This study proposes an approach to analyzing...
متن کاملReliability and Validity of the Pervasive Developmental Disorders Rating Scale and the Gilliam Autism Rating Scale
The psychometric properties of the Pervasive Developmental Disorders Rating scale (Eaves, 2003) and the Gilliam Autism Rating Scale (Gilliam, 1995) were investigated in this study. One hundred thirty-four individuals with autism, other pervasive developmental disorders, or conditions frequently confused with autism participated in the study. The results indicated that, with one exception, the r...
متن کاملValidity and Reliability of the Behavioral and Emotional Rating Scale (2nd Edition): Youth Rating Scale
Objective: This article reports findings of three studies addressing convergent validity and test-retest reliability of the Youth Rating Scale of the Behavioral and Emotional Rating Scale–Second Edition (BERS-2). Method: Pearson product–moment correlations were used in all three studies, the first two addressing convergent validity and the third addressing test-retest reliability. Results: Anal...
