Hello everyone! I am making a pre- and post-survey questionnaires and will be comparing the results. I am hoping to get some help on what is the best way make the surveys for analysis. I read/watched videos to make one survey with pre-test, educational material, and post-test. I also was told to make 2 separate links for pre-test and post-test. What would be the best way to go about this? If 2 links are the best way for analysis, how do I link the two separate surveys for analysis (eg. paired t-test)? If the answers are as detailed as possible as I am new to this platform, I would appreciate it greatly. Thank you!!

Hi 

as per my understanding you can try to use a common identifier between both the surveys and link that identifier in the second link using query string and can use workflow (email trigger) to distribute the second survey after pre survey

https://www.qualtrics.com/support/survey-platform/survey-module/survey-flow/standard-elements/passing-information-through-query-strings/
 

for example : customer_id is the unique indentifer in the survey1 . You can embed the customer_id in the survey 2 link using query string . That way you will be able to identify the responses.

 

please let me know if this works.

I think you should create links by yourself and distribute them so that the common identifier like user id is same for both the surveys. Then simply create a dashboard or report to view the trends in pre & post survey. Or go old school and match them side by side.

I agree with using two separate survey links and creating a dashboard view like @rgupta15 suggested. Within the dashboard, you could create a custom metric that tallies up a test score for each respondent. Then, you could create a table widget that shows the pre and post-test score for each respondent.

What is a dashboard?

Can I ask participants to create a unique identifier (Ex. 1234) at the beginning of pretest and then enter the identifier for post test and match the results up like that?

Looks pretty complicated. I’ll have to see if I can do this. Can I ask participants to create a unique identifier (Ex. 1234) at the beginning of pretest and then enter the identifier for post test and match the results up like that?

Hi @joh 

You need to ask participate to create unique identifier. You can assign it yourself . Use below mentioned functionality Random_id

Thank you for that. Using that, how can I link pretest data to posttest data. Should I ask the participants to enter their RandomID before they take the post test?

yes, you can add the question at the top of the post test asking participants to enter their RandomID given in the pre test survey.

And for safety at the end of the pre test survey show the participants their randomID

What is a dashboard?

A dashboard is just a view with multiple visualizations like charts and graphs. It can help to simply summarize your data at a quick glance. 

This link explains dashboards a little more: https://www.qualtrics.com/support/vocalize/getting-started-vocalize/vocalize-introduction/

Thank you so much. After matching the pre-and post test results with their RandomID, can Qualtrics measure/compare data from two different surveys and generate bar graphs etc?

Thank you for your reply. I read the page you linked but I am having such a difficult time understanding. Do you mind explaining to me in simple terms?

@Gaurav_27 @Shivamvig_sv Thanks for this thread.

Do you have a suggestion for a similar scenario (compare results for pre/post tests by student using an anonymous link they access on a web page [not a emailed to a contact list]) when the participants need to remain anonymous?

Thanks, Jill
