How we change what others think, feel, believe and do
There are many different types of question you can ask in a survey or interview.
Scale questions ask the subject to select an item or a value from a fixed scale.
How happy were you at work today? (please tick only one)
This is the basis of the very common Likert scale. These questions are useful for converting choice into a variable score which can be analyzed, for example discovering correlation with another variable.
Bipolar questions have a scale with two ends. The subject is asked to show bias towards either end.
What is your balance of preference here?
This type of question can be use to force choice between very similar items (thus causing a semantic differential choice) or very different questions.
Dichotomous (or binary) questions ask about black-and-white subjects, seeking only one of two answers. They are effectively scale questions with only two positions on the scale.
Did you vote in the last election?
