How do you do test-retest reliability in SPSS?
The steps for conducting test-retest reliability in SPSS
- The data is entered in a within-subjects fashion.
- Click Analyze.

How do you test inter rater reliability in SPSS?
Specify Analyze>Scale>Reliability Analysis. Specify the raters as the variables, click on Statistics, check the box for Intraclass correlation coefficient, choose the desired model, click Continue, then OK.
What is a high intraclass correlation coefficient?
A high Intraclass Correlation Coefficient (ICC) close to 1 indicates high similarity between values from the same group. A low ICC close to zero means that values from the same group are not similar.
How do you know if Inter-rater is reliable?
Inter-Rater Reliability Methods
- Count the number of ratings in agreement. In the above table, that’s 3.
- Count the total number of ratings. For this example, that’s 5.
- Divide the total by the number in agreement to get a fraction: 3/5.
- Convert to a percentage: 3/5 = 60%.
What is inter-rater reliability example?
Interrater reliability is the most easily understood form of reliability, because everybody has encountered it. For example, watching any sport using judges, such as Olympics ice skating or a dog show, relies upon human observers maintaining a great degree of consistency between observers.
How is the intraclass correlation coefficient used in R?
Intraclass Correlation Coefficient in R. The Intraclass Correlation Coefficient (ICC) can be used to measure the strength of inter-rater agreement in the situation where the rating scale is continuous or ordinal. It is suitable for studies with two or more raters.
How to run an intraclass correlation in SPSS?

How are intraclass correlations used to estimate interrater reliability?
Computing intraclass correlations (ICC) as estimates of interrater reliability in SPSS. The Winnower 2 :e143518.81744. DOI: 10.15200/winn.143518.81744
What are the reliability coefficients of ICC in SPSS?
Reliability Coefficients 4 items Alpha = ,9093 Standardized item alpha = ,9269. The value for ICC is 0.2898. The average measure ICC, i.e. when the scores of the four observers are averaged, is 0.6201. Cronbach α is 0.9093. The output does not provide variance components.
