Sample Answer
- Tables provide precise numerical data allowing for exact comparisons of heart rate values at specific time points, whereas graphs sacrifice some numerical precision for visual pattern recognition.
- Graphs effectively demonstrate trends in heart rate recovery over time, making the rate and pattern of recovery immediately visible, while tables require mental processing to identify these patterns.
- Tables can efficiently present multiple variables simultaneously (resting heart rate, maximum heart rate, recovery time) in an organised format, whereas multiple graphs might be needed to show the same range of data.
- Graphs are generally more accessible to audiences without statistical expertise, facilitating broader understanding of findings, while detailed tables may require greater numerical literacy.
