Conditional Sections

Watch Video Tutorial

This section is conditional. It will be included if the variable "Word" is "greater than or equal to" "delta". "Greater than or equal to" in this case, means the same as or after in alphabetical order. So "De" is "less than" "Delta", but "Deltas" is "greater than" "Delta". For numbers, ">=" works just like you'd expect.

By double clicking on a Section you can make it conditional.

The conditions under which a section appears are meant to read like a sentence:

Include (Skip) this section unless One (All) of the conditions below are met...

By changing Include to Skip you change the default behavior of the section. (If you just change Include to Skip and don't do anything else, the section will never appear.)

By default, only One of the conditions you specify has to be met. The other option is requiring All of the conditions to be met.

Note: if there are no conditions, All of the conditions will always be met, and One of the conditions will never be met.

You can add conditions by clicking the Add button. Each condition compares a variable to a value. A variable can be the name of a random variable or the column name of a question. (Remember, if the user hasn't answered the question yet, the variable will be empty.)

  19. You may want to put some items into Stimulus A and Stimulus B
  20. Test your questionnaire to see it work!

Testing

You might also like to add a section before Stimulus A and Stimulus B with a Text Response with the column name of Group so you can see what Group has been set to and change it for testing purposes.
