This set of Usability Engineering Multiple Choice Questions & Answers (MCQs) focuses on Usability Engineering Set 9
Q1 | Which of the following should an HCI expert take care of while designing aproduct?
- you can make as many assumptions as possible
- if it\s not obvious to the users, it’s always their fault
- you should not think yourself as a typical userd.
- the end user is never a beginner
Q2 | Which of the following instances illustrates ‘cognitive walkthrough’?
- talk to the users about their needs
- consult the experts
- imagine yourself as the user and think from their perspective
- none of the above
Q3 | Which of the following could be an example of a question in task analysis?
- what is your occupation?
- under what situations will you use an app like this?
- have you used a similar app?
- how would you change your profile picture in this app?
Q4 | What is an ideal composition of tasks in a task analysis?
- all easy tasks
- all difficult tasks
- a mix of easy, moderate and difficult tasks
- more easy tasks and less difficult tasks
Q5 | Identify the main goal of interaction design
- to assess the effect of interface on system
- to assess the extend of design functionality
- to sketch the system layout from user\s perspective
- to assess the extend and accessibility of system functionality
Q6 | Identify the evaluation technique that is useful to evaluate early design such as prototype and storyboard
- heuristic evaluation
- cognitive walkthrough
- model-based evaluation
- review-based evaluation
Q7 | Select the heuristic principle to describe the given statement below:Always keep user informed about what is going on, through appropriate feedback within reasonable time.
- error prevention
- help and documentation
- visibility of system status
- consistency and standard

- interview
- questionnaire
- research
- observation
Q9 | Using model of how a human would use a proposed system to obtain predict usability measure by calculation orsimulation."Choose the evaluation technique to describe the above statement

- dependent variables
- independent variables
Q14 | Independent variables is characteristic changed to produce different condition.Choose the example of Independent variablesi. Genderii. Interface style
- i, ii and iii
- i, ii and iv
- i, iii and iv

Q15 | Which is the best definition of an interaction paradigm?
- in broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., wimp, mobile, tangible)
- is used in the interface tohelp the user understand what to do (e.g., click on tabs to change window contents, use shopping cart
- inputs and receive information from the system (e.g., click and drag an object, talk to an object, move self closer to an object, converse with
- the conceptual model used to guide the design of the interface.
Q16 | Which is the best definition of an interaction mode?
- in broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., wimp, mobile, tangible)
- is used in the interface tohelp the user understand what to do (e.g., click on tabs to change window contents, use shopping cart
- inputs and receive information from the system (e.g., click and drag an object, talk to an object, move self closer to an object, converse with
- the conceptual model used to guide the design of the interface.
Q17 | What is an "affordance" according to Norman (1999):
- property of an object that indicates to people how to use the object.
- the return on investment of the usercentred design process.
- the opportunity cost of not using usercentred design.
- an instruction on an interface signalling how to use the interface.
Q18 | According to Rogers et al. (2011) what was the primary reason for the success of the iPod?
- powerful functionality
- user experience
- access to content
- conceptual design
Q19 | Which of the following is a design implication of our understanding of human attention?
- tactile feedback should make the same kinds of distinctions that a
person would feel in the world (e.g. pushing vs. pulling) - text should be legible anddistinguishable from its background under
different lighting conditions. - avoid cluttering the interface with more information than is needed at
the present moment for the user. - none of the above.
Q20 | A question format that collects users opinions on a verbal scale (eg. strongly disagree to strongly agree) is called what?
- a psychometric scale
- a likert scale
- a questionnaire
- an open-response questionnaire item.
Q21 | Sequential or series testing is
- running the system with line data by the actual user
- testing changes made in an existing or a new program
- is checking the logic of one or more programs in the candidate system
- making sure that the new programs do in fact process certain transactions according to specifications
Q22 | Which of these belong to the four criteria used to critique a cognitive walkthrough success or failure story:
- will the user be trying to achieve the right effect?
- will the user know that the correct action is available and will achieve the desired effect?
- . if the correct action is taken, will the user see that things are going ok?
- all of above
Q23 | Regarding the measurement of usability attributes:
- reliability is measured by performing common use cases
- errors are measured by counting minor and catastrophic errors made by users.
- learnability is determined by measuring the time it takes to explain an interface to a new user
- users are needed to measure efficiency
