Unit review questions
1. Calculate a paper-route average pace: Fictional case 5: gridDistance=40, elapsedSeconds=8. What is the modeled result using the stated method?
Need a hint?
  • Distance divided by elapsed time gives distance per time.
  • A larger model rate is not a diagnosis, safety judgment or body ranking.
2. Summarize a fictional accuracy fraction: Fictional case 5: matches=2, trials=5. What is the modeled result using the stated method?
Need a hint?
  • State the total trials; a match count alone is incomplete.
  • One fictional sample does not prove physical competence or transfer.
3. Choose a correction from a direction pattern: All offsets are+4,+2,+3 with one target. What fits?
Need a hint?
  • Inspect direction and spread, not only an average.
  • Keep target and criterion consistent before attributing a change.
4. Find the mean signed offset: Fictional case 5: offset 1=-1, offset 2=-2, offset 3=-3. What is the modeled result using the stated method?
Need a hint?
  • Retain signs and show the sum before dividing.
  • A zero mean can hide opposite errors; inspect the individual values.

Use the skills in a new task

Given offsets−3,0,+3 and 6 matches in 10 paper trials, report the mean, matching percentage and a warranted conclusion.

Work on paper or in your own document. Explain the choices you made.

  • Use the supplied facts without personal disclosures.
  • Apply at least two methods from this unit.
  • Show the sequence, calculation or evidence behind the decision.
  • Include a relevant boundary, help step or accessible alternative.
Compare with a model response

The signed mean is(−3+0+3)/3=0 grid units, but the results vary on both sides. 6/10*100=60% of recorded trials meet the criterion. No consistent one-sided correction is established, and no actual motor performance or transfer was tested.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
