Criteria Feedback
- The student framed a focused and feasible question within a clear school-based context.
- The student justified many methodological controls well, including counterbalancing, standardized warm-up, and recovery measurements.
- The student's procedure is detailed enough that another investigator could largely follow it.
- Some procedural steps remain ambiguous, especially the timing of rests and the way the metronome links to each movement cycle.
- A few controls are discussed as if they fully standardize the task, even though intensity likely still varied between participants and movements.
- The inclusion of sex in the question is not carried through into the analysis.

Criteria Feedback
- The student presents the data in a generally clear and organized way with tables, formulas, units, and error bars.
- The student makes a real effort to consider variability by using standard deviations and showing uncertainty on the graph.
- The student uses an appropriate paired test structure for repeated measurements from the same participants.
- Some processed values do not fully match the raw data, which affects trust in the calculations.
- The student's uncertainty treatment is incomplete, because instrument and timing uncertainties are noted but not systematically combined or interpreted.
- The analysis is not always precise, especially where the graph and tables do not show the full recovery profile.
