Collect useful data
Plan repeatable tests with variables, controlled conditions, measurement tools, and enough trials to support a claim.
POE Unit 4
Mission Performance: Statistics, Kinematics & Test Data
Use repeated trials, graphs, statistics, and kinematics to explain how aerospace systems move and perform.
Unit Purpose
What This Unit Prepares You to Do
Unit 4 focuses on using data to understand motion and defend engineering decisions.
Analyze performance
Use graphs, central tendency, variation, probability, speed, acceleration, and projectile calculations to explain what happened.
Defend decisions
Turn measurements into conclusions about reliability, consistency, accuracy, and possible design improvements.
