ReCal: reliability calculation for the masses

posted September 22nd, 2008 by dfreelon

ReCal (”Reliability Calculator”) is an online utility that computes intercoder/interrater reliability coefficients for nominal content analysis data. It is compatible with Excel, SPSS, Stata, OpenOffice, Google Docs, and any other database, spreadsheet, or statistical application that can export CSV files. Select one of the following two links to get started:

I need to compute reliability for two coders only. (ReCal2)

I need to compute reliability for three or more coders. (ReCal3)

ReCal is continuously updated to correct the errors users encounter, so if it doesn’t work for you today, check back in a few days; I might have fixed the problem. ReCal’s source code was last updated on 06/12/2009. To date, ReCal (2 and 3 combined) has been successfully executed a total of times by persons other than the author.

  2. This was very simple to use, and (I think) it worked beautifully. Thanks for building it and making it available.

  3. Wonderful tool, and I’ll recommended it to others. ReCal is especially helpful for data in an Excel spreadsheet, because Excel has no easy way for calculating intercoder reliability.

  6. This is so useful. I was looking everywhere for a decent app, and to have it web-based is just great!

    Thanks for helping me to beat deadline on a big (for me, anyway) conference paper.

  7. A very useful product, but I would strongly encourage you to give users a viable option for exporting the results. I have tried every way know to man and I just can get the data into a useful (reportable) format.

  8. Thanks. This was extremely helpful. So far I have only used the tool with sample data but will return when the second coder has finished.
