Unit 4 · Lesson 15 of 20
Interpret findings without overclaiming
Separate observed behavior, plausible explanation, severity, and confidence.

The idea
A finding reports what happened, under which task and conditions, and why it matters. Interpretation proposes a cause; it should remain separate from the observation. A small usability study can reveal a failure mechanism and guide revision, but its fraction of participants is not automatically a population failure rate. Look for alternative explanations and record what the prototype could not represent.
Assess severity by consequence, ability to recover, and which users or contexts are affected. A participant saying 'Paused' sounded like workout confirmation is evidence about their interpretation; it does not prove all runners hear it that way. Use the observation to make a targeted change and plan a retest that can disconfirm your explanation.
A count such as 'three of six' should be reported as a precise percentage for all users. In a small qualitative study, the count describes the sample and the observed failure mode.

Worked example
Fictional scenario
A smartwatch accepts 'pause workout' while someone runs; it can pause the workout timer or audio playback.
In a fictional six-person study, three triggered audio pause while the workout timer continued; two noticed only after another minute. An expert writes the observation and consequence, then hypothesizes that the command and 'Paused' response do not distinguish the target. They would inspect recordings and the assistant's intent logs before ruling out recognition errors.
Try a decision →03 / Decide
Guided decision
Which conclusion is supported by the fictional six-person study?
Feedback on your choice
What could change the answer: If intent logs show that the system consistently selected 'audio' before speaking, the command-disambiguation design becomes the focus; if it selected 'workout' but the timer kept running, the issue may be execution or feedback instead.
This feedback helps you examine the decision; it does not grade your written reasoning.

Independent application
Fictional scenario
A self-service kiosk test finds that two participants leave after a confirmation screen, while one asks staff whether the task succeeded.
Write an observation, at least two competing explanations, severity assessment, and a next check. Avoid turning the sample count into a general population rate.
Make: A finding card with observation, interpretation, impact, uncertainty, and next evidence.
The learner distinguishes observed behavior from cause, describes the study's limits, and chooses evidence that could change the conclusion.
