Creating an Anonymized Raffle

Warning: We recommend you take extra care when setting up surveys that involve incentives (e.g., setting up the anonymous raffles described on this page, use of the Tango Card extension, or setting up your own incentive survey). Using the correct settings and configuration is essential to ensure that the incentives are restricted to your intended respondents. Without appropriate settings, it may be possible for people to take advantage of your survey distributions and claim the incentives. Please carefully review the settings you can use to protect your survey on the Security Survey Options page.

About Creating an Anonymized Raffle

We often want to reward our respondents for helping us with our research. But most researchers also need to keep their data anonymous, so they can stay unbiased in their data analysis. Anonymizing data can also help keep us unbiased if we can only choose a few winners.

To create an anonymized raffle, you will need two surveys:

Survey One: Your main study. Totally anonymous. Asks consent before sending respondents to the raffle.
Survey Two: Raffle sign-up form.

Qtip: There are two versions of survey two. In one, you are responsible for randomizing a winner and sending the incentive yourself. In the other, Qualtrics will randomize and distribute for you, but you must use the Tango Card program to set up your incentives. You are always responsible for paying for the incentives.

Attention: Since this method uses two surveys, each respondent will generate two responses. Please keep this in mind for any response limits your account or license may have.

Survey One: Main Study

This is the main survey you are sending out to your respondents, which contains your primary study or feedback form.

Anonymizing Data

You can ensure your data collection is anonymous by distributing the survey through the anonymous link. If you are emailing the survey through Qualtrics, you can make sure your link type is anonymous.

However, the anonymous link still collects IP Address data. Select Anonymize responses under Security survey options to remove all personal data, including IP address.

Linking to the Raffle

You want to set the main study up so that once respondents get to the end, they can enter the raffle or opt out and get a standard thank you message.

At the end of your main study survey, add a multiple choice question asking if the respondent would like to enter a raffle.
Create your second survey, which will house the raffle.
Go to your second survey’s Distributions tab.
Select Get a single reusable link.
Copy the link.
Go back to your first survey using the dropdown in the navigation bar. Your first survey is the main survey where you will conduct your study.
Navigate to Survey flow.
Click Add a New Element Here or Add Below.
Select Branch.
Click Add a condition.
Select Question in the first field.
Select the question you created in Step 1.
Select Yes, or whatever you have named your choice that indicates consent.
Select Is Selected.
Click OK.
Click the Add a New Element Here that is indented under the branch.
Qtip: If you do not add a new element in the correct place, this set up will not work!
Select End of Survey.
Click Customize.
Select Override Survey Options.
Select Redirect to a URL.
Qtip: This feature is not available for free accounts.
Paste the anonymous link you copied from the second survey into the field.
Click OK.
Click Add a New Element Here at the bottom of your survey flow.

Qtip: Make sure you are adding the new branch at the end of the survey flow, and not indenting it under the first branch!
Select Branch.
Add a condition to your branch based on the question you created in Step 1.
Set as Yes Is Not Selected.
Qtip: Saying “Yes” “is not selected” specifies that if someone doesn’t answer the question, they will also get the non-raffle ending.
Click OK.
Indented under the branch, click Add a New Element Here.
Select End of Survey. You can customize this element however you like.
When finished, click Apply.

Survey Two: Manual Raffle

Qtip: This option requires that you randomly select a winner and contact them on your own. You will also be expected to provide your own incentives.

Go to your first survey, where the main study is.
Click the Distributions tab.
Copy the anonymous link.
Go to your second survey using the navigation menu.
In the Survey tab, click Survey options.
Go to Security.
Set Add a referral website URL to On.
Qtip: This step ensures your raffle contestants can’t give the survey link to just anyone! Only people who came from your previous survey can come here. However, please be aware that software is available for spoofing HTTP referers. To improve your survey’s security, you should combine this feature with other fraud detection measures, such as RelevantID.
Paste the anonymous link you copied in Step 3 into the field.
Navigate to the survey builder.
Click Add new question.
Change the question type to Form field.
Adjust the number of form fields.
Name your form fields and change the question text to capture your respondent’s contact information. Make sure you have an email field.
Qtip: You can add an additional question if you want! These steps just go over the essentials.
Click Publish in the upper-right of your survey to save these changes.
Qtip: If you do not have a Publish button, disregard this step.
Once you’ve collected your data, you can download a list of the participants by exporting the data.

Once you have your list of raffle winners, you will have to randomly select a winner and reach out to them with the incentive yourself.

Survey Two: Raffle Automated by Qualtrics

Qtip: This option requires that you have an account with Tango Card. You will be responsible for paying and setting up the incentives, but Qualtrics will take care of randomly awarding and sending the reward for you.

Attention: Although the Tango Card extension is included with most licenses, you will need to get the permission of an administrator to have it turned on. Contact your Brand Administrator to ask that the Tango Card Integration permission be enabled.

In this version, Qualtrics will automate the rewarding of a raffle for you.

Go to your first survey, where the main study is.
Click the Distributions tab.
Copy the Anonymous Link.
Go to your second survey.
In the Survey tab, click Survey options.
Go to Security.
Set the Add a referral website URL option to On.
Qtip: This step ensures your raffle contestants can’t give the survey link to just anyone! Only people who came from your previous survey can come here. However, please be aware that software is available for spoofing HTTP referers. To improve your survey’s security, you should combine this feature with other fraud detection measures, such as RelevantID.
Paste the anonymous link you copied in Step 3 into the field.
Navigate to the survey builder.
Click Add new question.
Change the question type to Form field.
Adjust the number of form fields.
Name your form fields and change the question text to capture your respondent’s contact information. Make sure you have an email field.
Qtip: You can add an additional question if you want! These steps just go over the essentials.
Go to Survey options.

Click Add Quota.
If given the choice, select Simple Logic Quota.
Change the first field to Embedded Data.
Type Raffle.
Select Is Equal to
Type Win.
From the dropdown, select None.
Change the maximum count to 1.

Qtip: This specifies that there can be only one winner of the raffle.
Click Save.
Go to the Survey flow.
Click Add a New Element Here or Add Below.
Select Randomizer.
Click Add a New Element Here below the randomizer.

Qtip: Make sure this element is indented under the randomizer!
Select Embedded Data.
Name the embedded data element Raffle.
Set the value as Win.
Add another embedded data element. Name this one Raffle, too, but make sure it is equal to Lose instead.
Click Duplicate on the embedded data to decrease the chances any one person coming into the survey will win.
Qtip: For example, if you have 10 embedded data total (including both win and lose), this is a 10% chance each new respondent who enters the survey will win. (Until someone wins. Changes we make in the following steps will ensure that once the prize is won, no one else can get it.) In contrast, if you have just one Win and one Lose, this increases the chance of winning to 50% for every new respondent.
Change the Randomly Present number to 1.
Select Evenly Present Elements.
Qtip: This will still randomize the order of elements.
At the bottom of the survey flow, click Add a New Element Here.

Qtip: Make sure this is not indented under the randomizer!
Select Branch.
Click Add a Condition.
Set the first field to Quota.
Select the quota you made earlier.
Select Has Not Been Met.
Click the plus sign ( + ) to add another condition.
Qtip: Do NOT change the “And” field.
Change the first field of the new condition to Embedded Data.
Type Raffle.

Choose Tango Card.
Select Respondent emails will be captured via a survey question.
Click the piped text button, {a}.
Select Survey Question, then the form field you made above, and then select the Email field.
Qtip: This ensures the email address a respondent enters is the same one that will receive the Tango incentive!
Click Continue and finish setting up the Tango Card task by following the linked instructions.
Back in the Survey tab, click Publish to preserve your changes.

If you test this survey, test in a copy. Otherwise, you will have to make changes to your Randomizer counts and your Quota counts.

Qtip: When testing this solution, you must use the anonymous link to your survey. You cannot test this with the preview version of your survey since the referral URL will not work for survey 2. However, please note that responses collected via anonymous link tests are billed to your license.

Qtip: This solution is not foolproof. Quota information is not saved until the respondent submits their survey, giving respondents time to change their answers or deliberate over their choices. Because more than one person can enter the survey at a time, there is a very small chance that two people submit the same answer at the same time, resulting in a quota that should have only had one registrant now having two. This is a rare occurrence.
