AgreeStat for Excel (Windows & Mac)
A Software for Analyzing the Extent of Agreement Among Raters with MS Excel
AgreeStat is a self-automated workbook that contains a VBA (Visual Basic for Applications) program, and therefore requires no installation. It is a point-and-click program that is easy to use, and that computes many well-known inter-rater reliability coefficients along with their standard errors. To use AgreeStat, choose one of the following 2 options:
|Note: AgreeStat-Windows has been successfully tested with both Excel 2007 and 2010. It may not work well with Excel 2003 and earlier versions of Excel.|
This is your ideal solution if your data contains missing values, or you want to compute weighted chance-corrected agreement coefficients with your own custom weights (as opposed to using standard linear or quadratic weights), or you want to compute intraclass correlation coefficients. With AgreeStat,
- You may compute Cohen's Kappa, Krippendorff's Alpha, Gwet's AC1, Fleiss' Kappa, and more ...
- You may compute Weighted agreement coefficients using a wide variety of weights, including Linear weights, Quadratic weights, Ordinal weights, Circular weights, and many more. Or specify your own Custom Weights as well. This feature is essential for researchers who want to implement their specific view of the nature of disagreements.
- You may compute Intraclass Correlation Coefficients with missing values.
- You will obtain inter-rater reliability coefficients along with their standard errrors, confidence intervals, and p-values.
Only a Few Steps from Data Entry to Finished Report
- From the screen shown below, choose the "2 Raters" or the "3 Raters or More" tab, depending on the number of observers involved in your study. Then specify the format in which you want to enter your data.
- Choose Your Method of Analysis and Select Your Data
- Specify the options you want for your analysis (Chance-corrected Agreement Coefficients):
- Enter a 2x2 Contingency Table
- Define the Intraclass Correlation Model
- Click on the Execute button, and get the results on the output worksheet
- When dealing with missing ratings (i.e. some observers do not score all subjects) then you must select the option "2 Columns of Raw Data" if dealing with 2 raters.
- If you want to capture your own custoim weights, you will use the following screen:
- Your can enter your ratings for 3 raters or more using the screen shown below. You will have the opportunity to select the workbook containing your data, as well as a specific worksheet.
