I can synthesize investigation evidence into a qualified design recommendation.
POE Unit 4 • Lesson 4.18
Final Data Analysis and Performance Review
Focus question: How can statistics, graphs, kinematics, and limitations support a final engineering recommendation?

Lesson Targets
What You Will Be Able to Do
Final mission-performance review
The review answers the mission question, uses correct analysis, compares results with criteria, and states limitations.
Activity Flow
How the Lesson Moves
Each step builds the data, motion, or testing reasoning required for today’s deliverable.
1. Select the evidence
Use the most relevant table, graph, calculations, and observations.
2. Evaluate performance
Compare accuracy, consistency, reliability, and criteria.
3. Defend the recommendation
State what should be used or revised and acknowledge limitations.
Lesson Interactive
Build the Final Performance Argument
Apply the lesson concept to a mission-performance scenario. Use the feedback to correct your reasoning before completing the main deliverable.
Final Design Comparison
Design A: 8/10 successes, mean range 4.96 m, standard deviation 0.18 m.
Design B: 9/10 successes, mean range 5.30 m, standard deviation 0.62 m.
Criterion: Land at 5.0 ± 0.3 m with consistent performance.
Order the Evidence Story
- Calculate and interpret the relevant statistics.
- State the design recommendation.
- Restate the mission question and criteria.
- Acknowledge a limitation and next test.
- Use the graph to identify the performance pattern.
- Summarize variables, controls, and test method.
- Present the repeated-trial data.
Build the argument from question and method through evidence, analysis, recommendation, and limitation.
Today’s Work
Main Deliverable
Final mission-performance review
Create one focused engineering artifact that demonstrates today’s learning.
- Present a clear chain from question and method to data, analysis, and recommendation.
- Include at least one limitation and a specific next-step test or design revision.

Mission Debrief
State the most important data-analysis or motion concept from today in your own words.
Name the measurement, calculation, graph feature, or test decision that supports your conclusion.
Identify one uncertainty, limitation, or next test that would strengthen the evidence.
