Uncertainty, Best/Worst Case Scenarios, and Rounding in Calculations

A set of QUESTION_AND_ANSWER flashcards covering uncertainty, best/worst-case scenarios, rounding, showing work, and interpreting different methods as described in the notes.

Why use best-case and worst-case scenarios in calculations?

To bound uncertainty by considering the most favorable and least favorable outcomes.

Why might rounding be done up (e.g., 22 to 23) in these notes?

To avoid underestimating results and to reflect a conservative estimate.

What does 'show your work' imply in these problems?

Provide the steps used to obtain the result so others can verify and accept the method.

What does the notes say about a 'different method'?

A different method is introduced; you may ignore it or use it, and then decide the final answer based on best/worst-case reasoning.

Which numbers were mentioned as examples derived from the equation?

2 and 0.5.

What determines the 'final answer' in the context of best/worst scenarios?

The final answer is chosen based on the scenario being used—either the best-case or worst-case result.

What does the difference between best and worst-case illustrate?

The level of uncertainty in the calculation.

What are the worst-case numbers mentioned in the notes?

23,000 or 2,130,000 as extreme outcomes in the example.
