✓Lesson Snapshot
Student Objective
I can organize repeated test results into a frequency distribution and histogram.
Main Activity
Convert a set of mission-distance or time data into a histogram and identify patterns in the results.
Deliverable
Frequency table and histogram
Tools / Materials
Notebook, calculator, graph paper or spreadsheet, sample data
1ProblemUnderstand the challenge and why it matters.
Repeated mission tests often produce a spread of values. Engineers need visual tools to see whether the data are clustered, spread out, or affected by outliers.
2ConceptLearn the engineering idea or skill.
A frequency distribution groups data into intervals. A histogram shows how often results fall within each interval, making performance patterns easier to interpret.
3ApplyUse the skill in a guided task.
Create a frequency table and histogram for a repeated-trial data set from a rover, projectile, terrain-course, or glider test.
4DocumentRecord your evidence and decisions.
Label the graph with title, axes, units, and interval widths. Add a short interpretation of the data pattern.
5ReviewCheck quality and identify your next step.
Your histogram should make the spread of performance easy to see.
