Criteria Feedback
- The student places the investigation in a clear and specific context with a focused population, task and exercise condition.
- The student explains why the chosen procedures fit the research question, linking the encoding task, recall timing and treadmill condition to memory and exercise theory.
- The student includes enough practical detail for another researcher to follow most of the procedure, including the participant group, speed, duration and materials.
- The student could make the allocation process and control of conditions clearer so the design can be reproduced without ambiguity.
- The student should define more precisely how script equivalence was judged and how any order effects were handled.
- The student would strengthen the method further by explaining how the design controlled for baseline differences more explicitly.

Criteria Feedback
- The student communicates the data using raw tables, a processed summary, a sample calculation and a graph, which makes the main pattern visible.
- The student correctly processes the raw scores into percentages, means and standard deviations, and they include statistical testing to compare the groups.
- The student shows awareness that variability matters by using spread measures and discussing the larger variation in the walking condition.
- The student needs to define the error bars more clearly so the graph can be interpreted unambiguously.
- The student's inferential analysis is weakened because the repeated measurements from the same participants are treated as independent.
- Some of the statistical justification and figure design reduce precision, especially where different units are combined on one axis.
