How to Convert Alchemer MaxDiff Data for Analysis in Displayr

In order to analyze the results of Alchemer MaxDiff analysis, you will need to first convert the data file.   

This article describes how to convert a MaxDiff data file provided by Alchemer (formerly known as Survey Gizmo) and add the responses to the main survey data set in a format suitable for analysis in Displayr.

Requirements

• An Excel Alchemer MaxDiff data file containing the following variables: Response ID, Combination, your Attribute variables with the shown attribute, and the Best and Worst selection variables.  
  
• Survey data set with a Response ID variable matching the MaxDiff data file.
  • If you don't have a survey data set, but still want to do the MaxDiff analysis: you can create a dummy dataset with one variable named Response ID for the unique response id numbers from the MaxDiff data. This is most easily done in Excel:
    
    
    

Please note these steps require a Displayr license.

Method

1. Import the survey data set into Displayr. See How to Import Data into Displayr.
2. Import the Alchemer MaxDiff Data into Displayr (e.g., Max Diff Output.xlsx).
3. In the Data Sources tree select the MaxDiff data set. 
   
4. In the Anything menu go to Advanced Analytics > MaxDiff > Convert Alchemer (Survey Gizmo) MaxDiff Data for Analysis.
5. Select OK.  You will now get the following message:
   
   This means you will have new best/worst MaxDiff variables and a MaxDiff version variable created in your survey data data set:
   
   And there will be a new page added that contains the MaxDiff Experimental Design information in a table:
   

6. If there is more than one other data set containing Response ID then the respondent data set must also be selected.

7. Use the outputs in step 5 as the inputs in the steps in either How to Use Hierarchical Bayes for MaxDiff or How to Do MaxDiff Latent Class Analysis.
   
   1. EXPERIMENTAL DESIGN > Design source > Use an existing table and Design is the table output on the new page.
   2. RESPONDENT DATA > Version > Version from ________.csv varaibles and Best/Worst selections >Choices from _________.csv
