What is measured using a Cohen’s kappa statistic?

Cohen’s kappa coefficient (κ) is a statistic that is used to measure inter-rater reliability (and also intra-rater reliability) for qualitative (categorical) items.

How can I present my Kappa result?

To analyze this data follow these steps:

1. Open the file KAPPA.SAV.
2. Select Analyze/Descriptive Statistics/Crosstabs.
3. Select Rater A as Row, Rater B as Col.
4. Click on the Statistics button, select Kappa and Continue.

How are the scores calculated in the SPSS?

In this example, these are: (1) the scores for “Rater 1”, Officer1, which reflect Police Officer 1’s decision to rate a person’s behaviour as being either “normal” or “suspicious”; and (2) the scores for “Rater 2”, Officer2, which reflect Police Officer 2’s decision to rate a person’s behaviour as being either “normal” or “suspicious”.

How many paired observations are there in a SPSS study?

A single paired observation reflects the assessment of “Doctor 1” for “Patient 1” compared to the assessment of “Doctor 2” for “Patient 1” (i.e., they are comparing the same patient). With 30 patients in the study, this means that there are 30 paired observations.

What are the assumptions in the SPSS procedure?

Assumption #1: The response (e.g., judgement) that is made by your two raters is measured on a nominal scale (i.e., either an ordinal or nominal variable) and the categories need to be mutually exclusive.

Which is one SPSS computes is not clear?

Which one SPSS computes is not clear although the formula is not that complicated so it could be checked by hand if the documentation is not explicit. Note that testing the hypothesis κ = 0 is usually superfluous as if there is a serious possibility that it might be zero the agreement must be trivially small.
