As the name makes clear, quantitative pages enable users to create questions where participants will be answering simply by typing a number. Each quantitative page can hold one or more questions as long as all of them require a quantitative answer.
There are two different ways to set up quantitative questions: on the same page, you can either have “single” questions that are not connected to each other or you can create a group of connected questions. Depending on the approach followed, in the next rounds, Welphi will aggregate data from participants answers in two distinct ways:
- Single question: Welphi will leave each question alone in one page and each question will have its own aggregated results (data from all participants) chart.
- Group questions: Welphi will group these questions on the same page and the aggregated results for these questions will be combined in one single data chart.

Regardless of how many questions you place in one page and the organization you have set up, you can always add a common introductory explanation for the page by filling the text box on the left side of the Quantitative page setup screen.
Please note that if you have setup a quantitative page in a previous round, you can only edit some details for that page on later rounds. More on this below.
Setting up quantitative questions
A quantitative question can easily be set up just by dragging a new question from the toolbox to the page area on the right (see image below).
Drag & drop to add questions to the page
Once you do this, you can start filling the question details:
- Question text – This is the only mandatory field and is where you write the actual question being asked to participants.
- Question Range (Min and Max) – For each question you can provide the range within which all participants answers have to fall. Note that , if both a minimum value and maximum value are set, participants will only be able to move forward in their questionnaires if their answers fall in the defined range. When you don’t set these fields, participants are free to write any number but will not be able to make use of the slider controls.
- Units – If you want to provide participants with the units being used for their answer, just write it on this box. Remember, this information will take some space on the questionnaire page so try use a single word and move further necessary explanations for the question text itself.
Quantitative question setup
Quantitative questions can be grouped to lock them together throughout all rounds. To do this, first drag a “Question group” to the page, and then place your quantitative questions inside the group’s questions area.
Below you can find an example of a page where both grouped and ungrouped questions where added. You can see that all questions were kept on the same page for the first round (see image at the top) but different procedures are followed for the two on the second round, as explained before.

- Round 1
Show Slider – Checking this box will show a slider control to help participants provide their answers. All questions in the page will have the slider control unless they don’t have their range setup, in which case the slider will not be visible and the range will be shown instead.
- Next rounds
Users can edit answers – Leaving this box unchecked will prevent users from changing their answer from the previous round. This can be helpful when you want to promote users interaction during a round, for example by using a forum control, and let them change their opinions on a later stage only.
Show Forum – The forum control is a live interactive chat control. Once you check this box, you will be able to add forum topics you want your participants to focus on. You can also create new topics after the round has started.
Show chart – As long as you had the same page on a previous round, you can check this box to automatically include a chart with all participants answers aggregated data. Depending on the set up you have chosen, the chart will either show information for a single question or all questions from a group.
Show Slider – Same as Round 1, above.
