Q171.
What is the main advantage of using closed questions, such as scalar, ranked, or multi-choice, in a questionnaire?

a.

They encourage respondents to provide detailed explanations.

b.

They reduce the need for pilot testing.

c.

They make the questionnaire shorter in length.

d.

They reduce the effort required by providing alternative responses.

Discuss
Answer: (d).They reduce the effort required by providing alternative responses. Explanation:Closed questions provide respondents with predefined alternative responses, reducing the effort required from them and potentially encouraging a higher response rate.
Q172.
Why is it important to conduct a pilot study for a questionnaire before distributing it to a larger user population?

a.

To ensure that the questionnaire design is flawless.

b.

To test the questionnaire on a representative sample of respondents.

c.

To determine the exact response rates.

d.

To identify and address any issues with the questionnaire design.

Discuss
Answer: (d).To identify and address any issues with the questionnaire design. Explanation:A pilot study helps identify and address any issues with the questionnaire design before distributing it to a larger user population, ensuring that the questions are comprehensible and that the results are as expected.
Q173.
What is the typical return rate for questionnaires distributed to users?

a.

Around 5–10%

b.

Around 15–20%

c.

Around 25–30%

d.

Around 40–50%

Discuss
Answer: (c).Around 25–30% Explanation:The typical return rate for questionnaires distributed to users is around 25–30%. This low return rate emphasizes the need to distribute questionnaires to a larger number of potential respondents.
Q174.
How can questionnaires be distributed to potential respondents via the internet?

a.

By distributing printed copies at relevant locations.

b.

By sending personalized emails to potential respondents.

c.

By conducting in-person interviews with potential respondents.

d.

By randomly selecting potential respondents from a website.

Discuss
Answer: (b).By sending personalized emails to potential respondents. Explanation:Questionnaires can be distributed to potential respondents via the internet by sending personalized emails or making them available on a website. This allows for wider reach and convenience.
Q175.
How can the level of representativeness of questionnaire respondents be determined?

a.

By analyzing demographic information collected from respondents.

b.

By selecting respondents randomly from a pre-defined list.

c.

By conducting follow-up interviews with respondents.

d.

By distributing questionnaires through postal mail.

Discuss
Answer: (a).By analyzing demographic information collected from respondents. Explanation:The level of representativeness of questionnaire respondents can be determined by analyzing demographic information collected from the respondents themselves.
Q176.
What is the main advantage of using eye tracking for usability evaluation?

a.

It provides direct insight into users' cognitive processing.

b.

It measures users' emotional responses.

c.

It eliminates the need for user feedback.

d.

It focuses on physical interactions with the interface.

Discuss
Answer: (a).It provides direct insight into users' cognitive processing. Explanation:Eye tracking allows researchers to directly observe users' cognitive processing by tracking their eye movements, providing insights into how users interact with the interface.
Q177.
How have recent advancements in eye tracking technology made it more suitable for usability testing?

a.

By using invasive eye caps for accurate tracking.

b.

By requiring participants to wear head-mounted cameras.

c.

By allowing non-contact monitoring with desk-mounted cameras.

d.

By reducing the resolution of eye tracking data.

Discuss
Answer: (c).By allowing non-contact monitoring with desk-mounted cameras. Explanation:Recent improvements in eye tracking technology involve non-contact monitoring with camera and light sources mounted in desk units, eliminating the need for invasive procedures or head-mounted devices.
Q178.
Which of the following measurements related to eye movement can provide insights into users' interaction with an interface?

a.

Count of mouse clicks performed during the session.

b.

Number of times users scroll through a webpage.

c.

Number of fixations and fixation duration.

d.

Time taken to complete a specific task.

Discuss
Answer: (c).Number of fixations and fixation duration. Explanation:Measurements such as the number of fixations (stabilized eye positions) and fixation duration can help understand how users interact with an interface and indicate areas of potential difficulty.
Q179.
What is a "scan path" in the context of eye tracking?

a.

The speed at which users move their eyes between fixations.

b.

A specific measurement of emotional engagement.

c.

A graphical representation of areas where users looked, their search strategy, and cognitive load.

d.

The sequence of physical interactions users perform on the interface.

Discuss
Answer: (c).A graphical representation of areas where users looked, their search strategy, and cognitive load. Explanation:A scan path is a visual representation that shows where users looked, how often, and for how long. It helps understand users' search strategy and cognitive load while interacting with an interface.
Q180.
What is a potential limitation of using eye tracking for usability evaluation?

a.

Eye tracking equipment is very affordable and widely available.

b.

Eye tracking does not provide accurate data on users' eye movements.

c.

Interpretation of eye movement measurements requires further research.

d.

Eye tracking is limited to studying physical interactions only.

Discuss
Answer: (c).Interpretation of eye movement measurements requires further research. Explanation:While eye tracking holds promise for usability evaluation, interpreting the meaning of different eye movement measurements requires more research. It's important to accurately understand the implications of users' gaze patterns.
