SEQSingle Ease Question
One question right after a task in a test: how difficult or easy it was, on a 1 to 7 scale. The simplest standardised way to compare how hard tasks are.

What it is
SEQ adds to what you see in behaviour: people can complete a task and still find it hard. Those are the tasks worth simplifying before people start to leave.
With its fixed wording and scale, it can be compared across tasks, versions and tests.
Exact question wording
The standardised wording Tack uses in English and Czech. Change it and the results stop being comparable.
English
Overall, how difficult or easy was this task?Scale 1 to 7: Very difficult … Very easy
Czech
Celkově, jak obtížný nebo snadný byl tento úkol?Scale 1 to 7: Velmi obtížný … Velmi snadný
How it is calculated
SEQ = the mean of answers 1 to 7 (1 = very difficult, 7 = very easy).
How to read the result
- Tack places the mean in bands: from 5.8 good, from 5.2 average, below 4.6 the task is hard for people.
- With five participants SEQ is only a guide. The calculator shows how wide the confidence interval is.
When to use it
- After every task in a usability test.
- When comparing two versions of the same task.
Frequently asked questions
Why is 7 easy and not difficult?
The standard SEQ has a fixed polarity: 1 is very difficult, 7 very easy. That keeps results comparable with other tests. Tack never flips it.
Can I reword the question?
You can, but then it is no longer the standard SEQ and the results cannot be compared with the bands or other tests. In the studio a reworded question stops counting as SEQ.
