OSU Engineering 1181 Final

What are the two main benefits of using user-defined functions?

(1) Allows multiple people to work on the same project seamlessly (2) Improve readability and reduce overall amount of code.

What are four benefits to working in a team?

(1) Many problems are solved better as a team (2) Other team members may think of ideas you did not (3) Broader range of possible solutions can be created (4) Each team member may bring a unique skill set which helps w/ idea generation (5)Team members can offer 'fresh eyes' to help when you are stuck on a problem

Two situations a programmer will choose to use a while loop in their code over a for loop

(1) Used when the # of passes is not specified (2) When looping continues until a stated condition is satisfied

What percentage is within one standard deviation of the mean?

68%

A condition statement is what?

A command that allows MATLAB to make a decision of whether to execute a group of commands following that statement

What are some strategies for successful dialogue between team members?

Active listening, Mutual Learning Perspective, constructive space (not destructive), understanding vs. Changing

What 5 qualities make a good team member?

Always reliable, Communicates with confidence, Does more than asked, adopts quickly and easily, displays genuine commitment

What are some items to consider when planning presentations?

Audience, Message & Supporting details, Purpose, Organization Strategy, Figures/Graphics/Illustrations, Other media?

Functions of graphics in presentations

Catch a readers attention and interest help writers communication the is difficult Help writers clarify and emphasize info Help non-native speakers understand info Help writers communicate info to multiple audiences with different interests

If you are plotting a graph with two lines are are some good graphing practices to distinguish between the two lines?

Change colors or line type. Plus a legend

What command clears the MATLAB workspace of all variables?

Clear all

What are the 6 main organization elements in a presentation?

Cover/Title Slide, Introduction to the speaker or team, Purpose statement/overview slide, The main "body", Conclusion/Recommendations, References

What does DrPIE stand for?

Define, Represent, Plan, Implement, Evaluate

What is included in the Evaluate section of DrPIE?

Does solution answer question? Is the magnitude reasonable, units correct? Can you verify by another approach or research?

What must be identified as you work through an ethical dilemma?

Issues and points of ethical conflict, protagonist, stakeholders, obligation to stakeholders, potential courses of action, consequences of different actions, why is something the best course of action?

What is the purpose of the Workspace in MATLAB?

It shows defined variable values

What is the function of the timekeeper team role?

Keeps the discussion on topic and on time

What is the definition of standard deviation?

Measure of dispersion of a set of data from its mean

Don'ts of verbal communication

Neglect visuals, Assume the audience understands, show your nerves/figit, read directly from screen or notes, use fillers or overly casual words.

What is included in the Implement section of DrPIE?

Perform dimensional analysis, work is organized and well-documented, display results appropriately, track progress.

Precise vs. accurate

Precise is that all of the answers are close to one another. Accurate in that the answers have a very low degree of error

Systematic vs. random error

Systematic error is still wrong but that answers are consistently wrong by the same degree of error. Random error is just random

Definition of Resolution?

The smallest measurable increment on a measured device

As a logical statement, is -1 considered true or false in MATLAB

True

True or False. A relational operator compares two numbers with a comparative statement such as 5<8 and evaluates if it is true or false?

True

True or False? Given the Matrix M, sum(M) returns a row vector with the sum of each column

True

What is included in the Define section of DrPIE?

What is the problem? What are the constraints? What is known/unknown, Make initial assumptions/estimates

What is the difference between an algorithm and a flow chart?

flowchart- visual set of steps algorithm- written set of steps

Compare and contrast for a while loops

for loops run for a set interval while while loops run until a condition is met. while loops must have variable declared before used in the conditional statement while for loops do not.

What is included in the Plan section of DrPIE?

potential tools, confirm assumptions, similarities to old problems?, underlying principles

What is included in the Represent section of DrPIE?

sketch/diagram/graph/flowchart/other graphic drawing of problem

Dos of verbal communication

tell stories, show passion, show personality, use themes and metaphors, polish your performance, use humor, Involve your audience

tax loopholes are: (legal, illegal, ethical, unethical)

unethically but legal
