Choosing the right question type

Jump to: SliderRange, 2D, Info TextChoice

There are plenty of different kinds of question types to choose from. To collect the most useful data, it's important to choose the right question type for each question. Here you can find an explanation for each type and what they are best for. 


The Slider is a popular and easy alternative to choice questions. It's good for respondents to choose more flexibly between two endpoints rather than choosing between preset choices. Respondents can move the slider handle to the point they think represents their opinion the most.

There are two kinds of sliders: Center slider and Zero slider. With the Center slider, the handle is located in the middle and in Zero slider it is located on the left end of the slider - point zero.

You can label the minimum and maximum values simply by typing them in the corresponding fields. Same goes with labeling the axis itself. For example, when the question is "my current mood":

  • Axis label: "Mood"
  • Max label: "Brilliant!"
  • Min label: "Not so good"


Click the Advanced icon to make more adjustments (optional):

  • Copy question settings from another question.
  • Set up minimum and maximum values for the question
  • Reset the values
  • Adjust step size
  • Toggle visibility to respondents
    • Axis minimum and maximum values
    • Answer value (on top of the slider handle)
    • Smiley indicator
Hint: The bigger the gap between min and max values, the 'smoother' the handle movement is. This is something to note when thinking about user experience.



The Range question type works very similarly to a slider. The difference with range type questions is that it allows the respondent to select a range of two values. This is particularly handy when building a product selector, where the respondent can select a suitable price range for their desired product.


The 2D question type is something that we at ZEF are very proud of. With 2D, respondents' opinions are measured in two dimensions. For example, in the X-axis, you can ask about the taste of the new coffee your company started to order. In the Y-axis, you can ask if the taste is really important for the respondent.

Our Z-Scoring method together with 2D questions helps you figure out which issues in your survey require your immediate attention and which ones you can ignore. For example, if one of your subject areas has performed poorly, but at the same time it's importance is low, it's nothing to worry about immediately. This feature is very popular among HR and customer satisfaction surveys.

When you have given your question or statement a name, proceed by giving the 2D axes their minimum and maximum labels. We recommend that you also give titles to the axes to make answering easier. Please see the picture below for an example. 


In the advanced settings, you can

  • copy settings from a previous question
  • set the minimum and maximum values for the axes
  • adjust the step size of the 2D answering field
  • toggle 
    • answer value visibility to respondents
    • smiley indicator on/off.

Info Text

When you want to inform your respondents about the purpose of your survey, give them feedback in the middle of the survey or give them instructions on how to answer, the info text question type is the way to go. Just go ahead and give your info text a title and write some text in the field:



Selecting the Choice question type lets your respondents choose from different options. Click Add choice to write down a new choice option. You can add multiple choices, and delete them by clicking the trash bin icon that appears next to the choice.


You can also give an option to evaluators to write their own option. That can be added by clicking Add "Other" Option on. The label for the textbox can be modified by writing the wanted text on the field Other.

In the Advanced settings, you can

  • determine the number of choices the respondent can pick
  • toggle visibility for selection limit
HINT: Don't forget about collecting feedback and different kinds of input, for example contact info, from your respondents. Learn more about input fields here.
