What is iteration in the design process?
Improving the aesthetics of a final design
Returning to earlier steps in the design process to refine a solution
Skipping the prototype phase
Ignoring test results
Which of the following is an example of a measurable criterion?
The design should be fun
The device should consistently travel 5 meters
The product should look appealing
The design should feel modern
A launcher produces 10 trials where 8 land very close to each other, but all are slightly off target. Which is correct?
High accuracy, low precision
High precision, low accuracy
Both high accuracy and precision
Neither accurate nor precise
Which statement is NOT true about a concept sketch?
It communicates design intent quickly.
It should show realistic proportions.
It must always be done digitally.
It makes communication easier.
In the Carnival Game project (1.1.5), what percentage of beanbag throws should result in a grand prize?
1–2%
3–5%
10–15%
20–25%
The design process is linear and does not require iteration. Is this statement true or false?
True
False
Sometimes true
Depends on the project
Mean, median, range, and interquartile range (IQR) are used in analyzing data by:
Summarizing and describing the distribution and spread of data.
Identifying the mode of the data set only.
Calculating only the highest and lowest values.
Determining the frequency of each data point.
Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other. An example of accuracy in engineering is calibrating a thermometer to read the correct temperature, and an example of precision is a machine consistently cutting metal rods to the same length.
Accuracy is how close a measurement is to the true value; precision is how close repeated measurements are to each other. Example: Calibrating a thermometer (accuracy), machine cutting rods to same length (precision).
Accuracy is how close repeated measurements are to each other; precision is how close a measurement is to the true value. Example: Machine cutting rods to same length (accuracy), calibrating a thermometer (precision).
Accuracy and precision both mean how close a measurement is to the true value. Example: Calibrating a thermometer and machine cutting rods to same length.
Accuracy and precision both mean how close repeated measurements are to each other. Example: Calibrating a thermometer and machine cutting rods to same length.
Which of the following are characteristics of effective peer feedback?
Specific, constructive, and respectful
Vague, critical, and dismissive
General, negative, and unhelpful
Ambiguous, judgmental, and irrelevant
The purpose of using a decision matrix in the Carnival Game project is to:
objectively compare different options based on specific criteria.
randomly select a game for the carnival.
track the scores of participants in the games.
design the layout of the carnival grounds.
A team records the following distances from the target (in cm): 4, 5, 6, 5, 7, 100, 6, 5, 4, 6. What is the mean of these distances?
14.8
5.3
6.2
10.5
What is the average distance from the origin (0,0) for the launches recorded at (2,3), (3,2), (1,4), and (2,2)?
3.25 units
2.5 units
4.0 units
2.0 units
Which of the following is a key criterion when proposing a design improvement for the bakery “Cupcake Party” packaging problems?
The solution must meet specific criteria and constraints.
The solution should ignore customer needs.
The solution must increase packaging costs.
The solution should reduce product quality.
Select the correct steps to follow when making a concept sketch and explain why selecting the correct front view is important.
Make light sketches, choose the best front view for clarity, add details, and label; the correct front view shows the most features clearly.
Start with heavy lines, ignore the front view, add random details, and skip labeling; the front view is not important.
Draw only one side, do not add details, and select any view; the front view does not affect the sketch.
Make rough sketches, select the least visible view, and avoid labeling; the front view is chosen randomly.
Ensuring your design is ethical in the Carnival Game project involves:
Considering fairness, safety, and honesty in the game's rules and implementation.
Making the game as difficult as possible to increase profits.
Ignoring player feedback and focusing only on revenue.
Copying designs from other games without permission.
