How do you find the intraclass correlation coefficient?

Intraclass correlation coefficient was first introduced by Fisher9 in 1954 as a modification of Pearson correlation coefficient. However, modern ICC is calculated by mean squares (ie, estimates of the population variances based on the variability among a given set of measures) obtained through analysis of variance.

What is intraclass correlation coefficient value?

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.

How to calculate intraclass correlations ( ICC ) in SPSS?

1. Decide which category of ICC you need. · Determine if you have consistent raters across all ratees (e.g. always 3 raters, and always the same 3 raters). If not, use ICC(1), which is “One-way Random” in SPSS. · Determine if you have a population of raters. If yes, use ICC(3), which is “Two-Way Mixed” in SPSS.

How to determine inter-rater reliability with the intraclass correlation coefficient?

This video demonstrates how to determine inter-rater reliability with the intraclass correlation coefficient (ICC) in SPSS. Interpretation of the ICC as an estimate of inter-rater reliability is reviewed. Loading…

Which is an example of an intraclass correlation?

Intraclass Correlation. The intraclass correlation coefficient, or ICC, is computed to measure agreement between two or more raters (judges) on a metric scale. The raters build the columns of the data matrix, each case is represented by a row. There may be two raters or or more. Typical example: RELIABILITY. /VARIABLES=r1 r2. /ICC TYPE(ABSOLUTE).

Which is an indicator of interrater reliability in SPSS?

Intraclass correlation (ICC) is one of the most commonly misused indicators of interrater reliability, but a simple step-by-step process will get it right. In this article, I provide a brief review of reliability theory and interrater reliability, followed by a set of practical guidelines for the calculation of ICC in SPSS. 1
