Dichotomous pairs

Dichotomous pairs have responses like:
  • Yes/No
  • True/False
  • Right/Wrong
  • Support/Oppose

These are very popular but they tend to have many problems and few good uses. The response options are very limiting and it is common to include double-barreled items, such as “Did you understand most of the workshop presentation and was it worthwhile?”

These responses are best used for directing individuals to a different part of a survey. For example, you can ask “Have you ever edited Wikipedia?” and if the respondent answers yes, they are directed to a set of questions for experienced Wikipedians.
