Please limit your answers to the space provided. Multiple Choice 1. According to the text, a team-based task where team members are trained to demonstrate very little information sharing and no coordination of task expertise would be exhibiting which aspect of team behavior? a) High Discrimination b) Low Discrimination c) High Integration d) Low Integration 2. According to text and lecture, which statement is most true about qualitative and independent variables? a) Qualitative variables cannot be used as levels of independent variables b ) Qualitative variables describe independent conditions differing in kind c) Independent variables can only have qualitative conditions to be valid d) Independent variables depend on changes in qualitative variable levels 3. In some course evaluation surveys at Purdue, students answer questions based on a 5- or 7- point scale ranging from “Strongly disagree” to “Strongly agree.” This is an example of what type of scaling? a) Nominal Scale b) Ratio Scale c) Likert Scale d) Qualitative Scale 4. Fitts’ Law (RT = a + b* (2D/W)) describes elements of cognitive and physical response during a control task. Which of the following terms best describes the meaning of D? a ) Distance to target b) Time required to act c) Distraction due to noise d) Relative target size Downloaded by Ayomide Sonoiki (ayosonoiki@gmail.com) lOMoARcPSD|11537756

IE 48600 Exam 2 Fall 2019 pg 3 2. Briefly explain the concept of Simplified English. Why, from an information processing perspective, would Simplified English be helpful in improving the task performance of both native- and non-native English speakers? 6-7 points: SE is a reduced version of English where fewer words are used, each word has only one meaning. (Extra if “controlled vocabulary” used). Since fewer words are used, and less ambiguity in meaning, even native speakers can access, recall, and process information faster with less error. 3. Explain why, according to the lectures and the textbook, pilot testing of questionnaires and surveys is important in systematic data collection. Poorly written or biased questions are useless, because the data are not systematic or valid. Pilot testing allows researcher to identify problems (6 points for answer up to here), including unexpected confusions, misunderstandings, or misinterpretation (extra if more than two listed). 4. Explain the difference between reliability and validity within a scientific and systematic approach to data collection. Provide an example of a measurement being reliable but not valid. 6-7 points for: Reliability is consistent, repeatable measure of phenomenon being studied so that there is confidence in score. Validity is that the measure is a good representation of what the phenomenon really is. Example: electronic thermometer or thermocouple stuck at 80F degrees due to fault, but real temp is >500F (happened in Apollo 13) (Extra if also noting MC 8 is an example) 5. Multiple choice question 5 above addresses the question of a child assembling a LEGO kit. According to lecture, is it the same type of error if the child intentionally decides not to use one of the pages of the instruction manual? Why or why not? 6 points: No, it’s not the same type of error, because intent was to do something other than procedure indicates. Extra 1-2 to indicate Reason’s VIOLATION.

IE 48600 Exam 2 Fall 2019 pg 4 ESSAY (do not exceed the space on this page) Describe the concept of function allocation. How does this concept relate to the concept of human supervisory control? How is function allocation between humans and automation similar/different to that between humans and humans in an organizational design and management paradigm of supervisory control? 16-17 point answers address the following: Function Allocation (FA) talks about who does what, when, and examines who is good at what, and what is safer / better / more efficient from an overall or integrated system perspective. This could be applied to humans as well as automation (when humans controlling automation that can repeatably do action, this can be described as human supervisory control {HSC}), because it’s still separating who is doing what in task. Organizational design and management (ODAM) addresses general aspects of who has what responsibility and how jobs performed at broader work analysis (not just narrow level of focused task under ideal conditions), including safety and health, work schedules, pace and pay. ODAM is not just manager taking advantage of worker (points taken off if answer suggests that F. Taylor or L. Gilbreth intended scientific management to be a negative ODAM approach to FA or HSC) Extra points for mentioning Fitts’ HABA / MABA; Sheridan and levels of automation; command and control – span of control; recognition of Hawthorne or Tavistock influences on ODAM studies of social interactions or sociotechnical adoption affecting FA or HSC.
