What is dichotomous scale?
A dichotomous scale is a type of survey response scale that provides two options, which lie at opposite ends. On a dichotomous scale, the survey respondent can not give a neutral answer because it is a case of either one or the other.

3 Types of Survey Response Scales
Which Survey Scale Should You use?
- It depends on the type of data you want. Dichotomous scales (“yes” or “no”) are great for precise data, but they don’t allow for nuance in respondents’ answers.For instance, asking if a customer was happy with an experience (yes or no), gives you almost no insight into how to improve the experience. A Likert Scale or Net Promoter Score (NPS) is bet...

Little Tweaks, Big Differences
- Almost any factor can influence the outcome of a survey, which is why Spool highlights the difficulty of accurate benchmarking data.

They gave the questionnaires to 10,000 people and found some interesti…

- Even though default ranges for survey questions seem arbitrary, there’s a lot of thought and design behind them. Whether you use a Likert scale, a dichotomous scale, or a semantic differential scale depends on what you’re trying to learn. In addition, when trying to obtain sensitive information like age or income, asking for exact numbers just won’t work (non-respons…
