combining data two surveys and different respondents

Depending on if you have a limit to the number of questions that you can have per survey, you can do this in one survey. Create all of your questions in one question block, then copy the question block until you have as many question blocks (with the same questions) as you will have respondents (so if you anticipate 10 people taking your survey, you should have 10 question blocks with the same questions). Then go to the survey options and select Scoring. Once the Scoring page loads, click the Scoring Options link on the top right of the page. Create a category for each question block (you can name them whatever you want):

Make sure that the checkbox next to Treat empty statistics for scoring categories as 0 is checked and then press the Save button. Next, make sure that the first scoring category that you created is selected in the category drop down menu at the top of the page, and score all questions in the first question block. Don’t add scoring for any other question blocks. After you add the scoring for the first question block, go back up to the Category drop down menu and select the second category that you created. Once you do that, the scores that you added for the first question block should go away. Add scoring for the SECOND question block (leave the first question block blank). Once you’re done with the scoring for the second question block, select the third category that you created from the Category drop down menu and add scoring to the THIRD question block (leaving both the first and second question blocks blank). Do this until you’ve scored all question blocks in different scoring categories. 

Next, go to the survey workflow, click the Add Below link in the first question block, and select Embedded Data. Once you do that, a green box titled Set Embedded Data will show below the first question block with the drop down already selected. Type the name of your first scoring category into the drop down field and then click the Set a Value Now link to the right. This will populate a new drop down menu. Click the arrow of the new drop down, hover over Insert Piped Text, hover over Scoring, hover over your first scoring category name, and then select Score:

Do the same thing for each question block, selecting the next scoring category each time (so the second question block will have the second scoring category, the third will have the third category, etc.). After you have all scoring embedded data set up, click the Apply button and go back to the Survey editor.

In the second question block, add a new text/graphic question at the beginning of the block. This is where you’ll add the notification of what the previous respondents scored. You can say whatever you want, but as an example, I typed this:

So, it’s “Hello Respondent B. Respondent A scored [piped text > scoring > score 1 (or whatever you named your first scoring category) > score] out of [total number of questions in each question block, not including the notification question]” (so if you ask 30 math questions and have the text/graphic question notifying of the previous respondent score(s), you will say 30). This will make it so that when a respondent starts the second question block, they will see the previous person’s score:

In the third question block, you’ll type the same statement, but you’ll either change the piped text to scoring > score 2 (or whatever you named your second scoring category) > score (if you only want each respondent to see just the previous person’s score) or you’ll ADD piped text for scoring for the second scoring category, so it would look like this:

Finally, at the end of each question block, add one more text/graphic question and insert a page break before it. In the new question, Give your end of survey instructions so that your respondent doesn’t continue on into the next person’s response. You can also let the respondent know what their own score was by adding piped text > scoring > scoring category for the same question block that you’re adding in > score. For example, the last question in question block three (for which I’ve named the scoring category Score 3) could say:

When you send out the survey, you’ll need to generate ONE personal link that you will send to everyone. After the link is generated, send it to your first respondent, wait until they finish the first question block, and then send the same survey link to Respondent B. When Respondent B clicks the link, they will automatically be taken to the first unanswered question, which should be the first question in question block 2. You’ll need to make sure that Allow Respondents to Finish Later is activated in your survey options, and you will need to give more time before the survey is considered complete, since you’ll be sending it to multiple people. You can have the back button enabled in the survey options if you want each respondent to be able to edit their responses because when you add the embedded data between blocks, it will prevent respondents from accessing the previous question blocks.
