What is an acceptable ICC for inter rater reliability?

What is an acceptable ICC for inter rater reliability?

Under such conditions, we suggest that ICC values less than 0.5 are indicative of poor reliability, values between 0.5 and 0.75 indicate moderate reliability, values between 0.75 and 0.9 indicate good reliability, and values greater than 0.90 indicate excellent reliability.

What does intraclass correlation measure?

Intraclass correlation measures the reliability of ratings or measurements for clusters — data that has been collected as groups or sorted into groups. A high Intraclass Correlation Coefficient (ICC) close to 1 indicates high similarity between values from the same group.

What is ICC value?

The ICC is a value between 0 and 1, where values below 0.5 indicate poor reliability, between 0.5 and 0.75 moderate reliability, between 0.75 and 0.9 good reliability, and any value above 0.9 indicates excellent reliability [14].

What are ICC values?

What is the difference between interclass and intraclass correlation?

Interclass correlation shows the association among the groups and intra-class correlation shows the association within a group. “Interclass” means among the groups. “Intra class” means within group.

What is the range of ICC?

between 0 and 1
The ICC is a value between 0 and 1, where values below 0.5 indicate poor reliability, between 0.5 and 0.75 moderate reliability, between 0.75 and 0.9 good reliability, and any value above 0.9 indicates excellent reliability [14].

What does the intraclass correlation coefficient ( ICC ) mean?

The intraclass correlation coefficient (ICC) is a descriptive statistic that describes the extent to which outcomes 1) within each cluster are likely to be similar or 2) between different clusters are likely to be different from each other, relative to outcomes from other clusters.

Which is an example of an intra class correlation?

The intraclass correlation is commonly used to quantify the degree to which individuals with a fixed degree of relatedness (e.g. full siblings) resemble each other in terms of a quantitative trait (see heritability).

How is the intraclass correlation used in ANOVA?

Beginning with Ronald Fisher, the intraclass correlation has been regarded within the framework of analysis of variance (ANOVA), and more recently in the framework of random effects models. A number of ICC estimators have been proposed. Most of the estimators can be defined in terms of the random effects model

Which is the correct formula for the ICC?

The ICC serves as a quantitative estimate of this aspect of reliability. Very generally speaking, the ICC is calculated as a ratio ICC = (variance of interest) / (total variance) = (variance of interest) / (variance of interest + unwanted variance).
