Estimating Inter-Rater Reliability with Cohen's Kappa in SPSS

This video demonstrates how to estimate inter-rater reliability with Cohen’s Kappa in SPSS. Calculating sensitivity and specificity is reviewed.

Many thanks for your clear explanation on the Kappa calculation and interpretation, Prof!

Fantastic explanation. Another string to my statistical bow. Thank you!

Thanks for your videos Dr Grande, always super helpful!

Thanks for your video. I have a question :
What does this error indicate ? "Kappa statistic cannot be computed. It requires a two-way table in which the variables are of the same type."
Despite I utilized a two-way table in which the variables are of the same type (both of them nominal), I get that from SPSS.
What should I do about that ?

Again like it better in SPSS than in Excel. This info helped some on specificity and sensitivity but I may have to cross-reference with the book.

Will definitely require more study to fully understand when to apply this technique and how to interpret the results. A helpful introduction however

I strugling with it now

Hey, I have a question for ya Todd! Is there a way to estimate inter-rater reliability with Krippendorf's alpha (kalpha) in SPSS?
Thanks!

[@MrJsanabria]

Dr. Grande: what would you do if Kappa is too low? Would you ask both coders to recode the data once again but now together going through every single item in order to agree with each other and increase the alpha? What do you suggest? Thanks in advance

Thank you Dr. Grande for this. I wonder what the differences are between Cohen's kappa and Cronbach's alpha? I know Cohen's kappa is good for dichotomous data whereas Cronbach's alpha can be used for continuous data, such as Likert scale rating?

Thank you for uploading it!

Is it possible to use Cohen's Kappa with more than two raters?

[@amir.hazwan]

I think Fleiss is more suitable for more than 2 raters.

Many thanks for making the video, Dr. Grande! I followed the steps in SPSS and got a negative number (-.143) for Cohen's Kappa. Just wondering what a negative number means?
