How do I choose between a rating scale and a set of answer choices?
Quick answer
Use a rating scale when you want to know the degree or frequency of something, such as how useful a resource was or how often someone used it. Use answer choices to identify a category, fact, or action, such as which format someone used. If several categories might apply, allow multiple selections. In either case, make the options clear and useful for the decision you plan to make.
The question, the details, the next step.
I’m writing a short feedback form. How can I tell whether a question needs a rating scale or a set of answer choices?
Start with what you want to learn. A rating scale asks respondents to place their experience on an ordered range: for example, “How satisfied were you with the instructions?” with options from “Very dissatisfied” to “Very satisfied.”
Answer choices are better when you want to identify a category rather than a degree. For example: “Which version of the instructions did you use?” with “Printed,” “On-screen,” and “Both.” Those choices identify types; they aren’t levels of satisfaction.
A quick test: if you want to compare levels, try a scale. If you want to count kinds of responses, try categories. Choose based on the answer you need, not which format looks more formal.
Could you show the difference with questions about the same topic?
The topic can stay the same while the information sought changes:
- Degree: “How easy was it to find the information?” Options: “Very difficult,” “Somewhat difficult,” “Neither easy nor difficult,” “Somewhat easy,” and “Very easy.” These responses form an ordered scale.
- Category: “Where did you look first?” Options: “Search,” “Navigation menu,” “Help page,” “Another source,” and “I didn’t look.” These identify different routes.
- Frequency: “How often did you use the guide this week?” Options: “Never,” “Once,” “Two or three times,” and “Four or more times.” These are ordered frequency bands.
- Preference: “Which format would you prefer?” Options: “Short written steps,” “A video,” “A diagram,” and “No preference.” These are categories. If several formats could suit someone, invite them to select all that apply.
Treat these as drafts: tailor the wording and options to what you need to learn.
What should I watch out for when I write the scale or its choices?
For a scale, keep the direction consistent and make the options understandable. Label the endpoints; label more points if people might interpret them differently. Include a neutral point only when a neutral answer makes sense for the question.
For categories, check that respondents can tell which option fits. If someone might not fit a listed option, consider “Other” with a write-in field. If more than one answer may apply, say so; if only one is allowed, make that clear.
Consider “Not applicable” when the question doesn’t fit the respondent, and “Don’t know” when they can’t provide the information. They mean different things, so include them only if they help you interpret responses. If the list is unwieldy, broader categories or a separate follow-up may be clearer.
Can you give me a quick way to review my draft before I send it out?
Finish the sentence “I need to know whether…” If it ends with a degree or frequency, try an ordered scale. If it ends with a type, choice, or circumstance, try categories. Then imagine answering your question: can you find an option that fits without guessing what the writer means?
For example, “How useful was the practice activity?” asks about degree, so a scale from “Not at all useful” to “Extremely useful” may fit. “Which activity did you complete?” asks for a category, so list the activity names and consider “I didn’t complete one.” If you also need to know how useful each activity was, ask that separately. Combining which activity someone did with how useful it was makes the answer harder to interpret.
Before using the form, check that the responses will help with the decision you plan to make. If you’re unsure how readers understand the wording, ask a few people to explain what they think a question is asking.
A practical checklist
Name the information you need from each response.
Use an ordered scale for degree or frequency; use categories for types or alternatives.
Make options clear and appropriate to the question.
State whether respondents should choose one answer or select all that apply.
Add “Other,” “Not applicable,” or “Don’t know” only when useful.
Check that the answers can inform your intended decision.
A few more useful answers
Can answer choices form a rating scale?
Yes. A scale may be presented as selectable answers; what makes it a scale is that the options represent ordered degrees or frequencies. Categories identify different kinds of answers.
Should I use numbers for a rating scale?
You can, but numbers alone may not explain what each point means. Label the endpoints, and label additional points if readers might interpret them differently.
What if respondents may select more than one category?
Allow multiple selections and say “Select all that apply.” If you need to know which option matters most, ask that separately.
