Questions people ask
How is a SUS score calculated?
For odd-numbered statements, subtract 1 from the answer; for even-numbered ones, subtract the answer from 5. Add the ten results and multiply by 2.5 for a score from 0 to 100; about 68 is average. The form collects the answers and you work out the score from the CSV download, since Ribbit doesn’t score responses.
Why do the statements switch between positive and negative?
Odd statements are positive and even ones negative, so people read each one instead of agreeing with everything. That’s why the scoring treats them differently.
Can I change the wording?
You can change anything once it’s a draft in your workspace. To compare your score with other SUS results, keep the ten statements, their order and the 1–5 scale; replacing “this product” with your product’s name or “the website” is fine.
When should I send it?
Right after someone has finished a usability test or a first real session, while it’s fresh. The score tells you how usable it feels; the open question at the end tells you why.
