b.

It provides information at the wrong level of detail.

c.

It lacks participant interaction.

d.

It does not capture visual data.

Discuss
Answer: (b).It provides information at the wrong level of detail. Explanation:One limitation of data obtained via direct observation is that it may provide information at the wrong level of detail.

a.

To provide a real-time analysis of user actions.

b.

To record the participant's actions during a task.

c.

To obtain a participant's interpretation of their actions after the task.

d.

To automate the data collection process.

Discuss
Answer: (c).To obtain a participant's interpretation of their actions after the task. Explanation:The primary purpose of a post-task walkthrough is to obtain a participant's interpretation of their actions after completing a task. It aims to gain insights into why certain actions were performed and may involve replaying the recorded transcript to the participant.
Q153.
Why might a delayed walkthrough be preferred over an immediate one?

Q154.
In what situations might a post-task walkthrough be particularly useful?

a.

When participants prefer to communicate during observation.

b.

When the task is simple and straightforward.

c.

When the task is too intensive for real-time commentary.

d.

When participants are experienced with the system.

Discuss
Answer: (c).When the task is too intensive for real-time commentary. Explanation:A post-task walkthrough can be particularly useful when the task is too intensive or critical for participants to provide real-time commentary. It allows them to reflect on their actions and provide insights after the task is completed.
Q155.

What is a key advantage of using query techniques in interface evaluation?

a.

They provide objective and quantitative data.

b.

They are completely automated and require no human interaction.

c.

They get the user's viewpoint directly and may reveal unanticipated issues.

d.

They focus exclusively on the designer's perspective.

Discuss
Answer: (c).They get the user's viewpoint directly and may reveal unanticipated issues. Explanation:A key advantage of using query techniques in interface evaluation is that they get the user's viewpoint directly and may reveal issues that were not anticipated by the designer.
Q157.
Which type of query technique involves asking users a set of prepared questions and allowing them to elaborate on their responses?

a.

Interviews

b.

Observations

c.

Experiments

d.

Surveys

Discuss
Answer: (a).Interviews Explanation:Interviews involve asking users a set of prepared questions and allowing them to elaborate on their responses. This method enables evaluators to gather detailed information directly from users.
Q158.
What is the primary advantage of using interviews for evaluation?

a.

Interviews provide quantitative data for statistical analysis.

b.

Interviews are less time-consuming than other techniques.

c.

Interviewers can control the user's actions during the session.

d.

Interviewers can probe deeply and ask follow-up questions based on user responses.

Discuss
Answer: (d).Interviewers can probe deeply and ask follow-up questions based on user responses. Explanation:The primary advantage of using interviews for evaluation is that interviewers can probe deeply and ask follow-up questions based on user responses. This allows for a more detailed exploration of user experiences.
Q159.
How can interviews be structured to ensure consistency and focus during the evaluation process?

a.

By asking only leading questions to guide users' responses.

b.

By avoiding any prior preparation to keep the interview spontaneous.

c.

By adapting the interview form for each user individually.

d.

By planning a set of central questions in advance and structuring each interview around them.

Discuss
Answer: (d).By planning a set of central questions in advance and structuring each interview around them. Explanation:Interviews can be structured for consistency and focus by planning a set of central questions in advance and structuring each interview around these questions. This approach helps maintain a consistent base between interviews while allowing adaptation to each user's responses.
Q160.
Which of the following is a limitation of using interviews for interface evaluation?

a.

Interviews provide objective and definitive insights into user behavior.

b.

Interviews can be administered quickly and with minimal preparation.

c.

Interviews may yield subjective and potentially biased information.

d.

Interviews are limited to asking closed-ended questions.
