Q51.
What limitation of laboratory studies can affect the accuracy of observations made during evaluation?

a.

Lack of context and natural interruptions

b.

Replication of interpersonal communication

c.

Availability of sophisticated audio/visual equipment

d.

Increased familiarity of participants with the system

Discuss
Answer: (a).Lack of context and natural interruptions Explanation:The limitation of laboratory studies is the lack of context and natural interruptions that occur in users' real work environments, which can affect the accuracy of observations made during evaluation.
Q52.
Which expert-based evaluation approach involves evaluators stepping through a sequence of user actions to identify potential usability problems?

a.

Cognitive walkthrough

b.

Heuristic evaluation

c.

Model-based evaluation

d.

User participation

Discuss
Answer: (a).Cognitive walkthrough Explanation:Cognitive walkthrough is an expert-based evaluation approach where evaluators step through a sequence of user actions to identify potential usability problems.
Q53.
What is the primary focus of cognitive walkthroughs in terms of user interaction?

a.

Exploring user motivations

b.

Evaluating system aesthetics

c.

Assessing system functionality

d.

Analyzing error messages

Discuss
Answer: (c).Assessing system functionality Explanation:The primary focus of cognitive walkthroughs is to assess how easy a system is to learn and explore, especially through user exploration.
Q54.
What is the primary goal of heuristic evaluation?

a.

Assessing system functionality

b.

Identifying actual user behavior

c.

Predicting user performance

d.

Evaluating system aesthetics

Discuss
Answer: (c).Predicting user performance Explanation:The primary goal of heuristic evaluation is to predict user performance by identifying usability problems using a set of general heuristics.
Q55.
What scale is commonly used to rate the severity of usability problems identified through heuristic evaluation?

a.

0-2-4-6

b.

1-3-5-7

c.

0-1-2-3

d.

0-1-2-4

Discuss
Answer: (c).0-1-2-3 Explanation:The severity of usability problems identified through heuristic evaluation is often rated on a scale of 0 to 3, where 0 indicates no problem and 3 indicates a major usability problem.
Q56.
What is the purpose of using previous studies in evaluation?

a.

To replace usability testing with actual users

b.

To validate the expertise of the evaluators

c.

To compare experimental conditions

d.

To provide evidence-based support for design decisions

Discuss
Answer: (d).To provide evidence-based support for design decisions Explanation:Using previous studies in evaluation allows designers to use existing experimental results and empirical evidence as evidence-based support for design decisions.
Q57.
Which evaluation style involves observing the interaction between users and systems in their natural work environment?

a.

Laboratory studies

b.

Controlled experiments

c.

Field studies

d.

Contextual analysis

Discuss
Answer: (c).Field studies Explanation:Field studies involve observing the interaction between users and systems in their natural work environment, retaining the context of actual use.
Q58.
What is a key advantage of field observation over laboratory studies in usability evaluation?

a.

Controlled environment

b.

Reduced noise levels

c.

Fewer interruptions

d.

Natural context and interactions

Discuss
Answer: (d).Natural context and interactions Explanation:Field observation provides a natural context and allows observation of interactions that would occur in real-world situations.
Q59.
In the context of field observation, what is the "Heisenberg uncertainty principle" referring to?

a.

The influence of the observer on participants' behavior

b.

The difficulty of maintaining controlled conditions

c.

The need for recording equipment

d.

The impact of contextual information

Discuss
Answer: (a).The influence of the observer on participants' behavior Explanation:The "Heisenberg uncertainty principle" in field observation refers to the influence of the observer and recording equipment on participants' behavior.
Q60.
When might laboratory testing be more suitable than field observation for usability evaluation?

a.

When studying long-term tasks

b.

When observing natural context

c.

When studying complex interactions

d.

When evaluating specific interface features

Discuss
Answer: (d).When evaluating specific interface features Explanation:Laboratory testing can be more suitable for evaluating specific interface features, as controlled experiments are normally conducted under laboratory conditions.
