Ballpark offers three specialised question types that ensure participants respond in a specific format: number, email, and date. Each one validates the input automatically, so you get clean, consistent data.
Number questions
Number questions restrict responses to numerical values. They are useful for collecting ages, quantities, frequencies, income, or price sensitivity data.
Open your study and go to the Build tab.
Click Add step.
Select Number.
Type your question and add a description if needed.
Participants can only enter digits, so you will not need to clean up text responses later.
Email questions
Email questions validate that the response follows a standard email format. They are useful when you need to follow up with participants or send incentives.
Open your study and go to the Build tab.
Click Add step.
Select Email.
Type your question.
The built-in validation means participants cannot submit an improperly formatted email address.
Date questions
Date questions let participants enter a date in a consistent format. They are useful for scheduling, collecting birthdates, or recording when something happened.
Open your study and go to the Build tab.
Click Add step.
Select Date.
Type your question.
Additional options
For all three question types, you can click Options and enable Make required to ensure participants complete the step before continuing.
Tips
Use number questions instead of open text whenever you expect a numeric answer. This makes your data much easier to analyse.
If you are collecting email addresses, let participants know why. People are more willing to share contact details when they understand the purpose.
Number, date, and rating scale questions all support conditional logic rules like “is equal to,” “is less than,” and “is greater than.”
Next steps
For questions that need a free-form written answer, use an open text step. If you need participants to agree to terms before continuing, see legal consent questions.
