✓Lesson Snapshot
Student Objective
I can calculate and interpret measures of central tendency and range for aerospace test data.
Main Activity
Use repeated mission results to calculate mean, median, mode, and range, then compare what each value tells an engineer.
Deliverable
Central tendency calculation sheet
Tools / Materials
Notebook, calculator, sample data, measurement data sheet
1ProblemUnderstand the challenge and why it matters.
A design team needs more than one measurement to describe performance. Different statistics can tell different stories about the same data set.
2ConceptLearn the engineering idea or skill.
Mean, median, and mode describe typical performance. Range describes spread between the smallest and largest values.
3ApplyUse the skill in a guided task.
Calculate mean, median, mode, and range for a repeated-trial data set and decide which statistic best supports an engineering claim.
4DocumentRecord your evidence and decisions.
Show all calculations with units and write a short recommendation based on the results.
5ReviewCheck quality and identify your next step.
Your recommendation should explain both performance and consistency.
