Sample Answer – Any 3 of the following

  • The qualifications and expertise of the researcher administering the tests directly impacts credibility, as proper protocol execution requires technical knowledge and experience with specialised equipment to ensure accurate VO₂ max measurements.
  • The reputation and calibration status of testing equipment significantly affects credibility, as validated, regularly calibrated equipment provides more trusted results than uncalibrated or consumer-grade alternatives.
  • Sample size and selection methods influence the credibility of findings, as larger, representative samples with appropriate inclusion/exclusion criteria yield more believable results than convenient or biassed selections.
  • Transparency in reporting of methods, including detailed documentation of testing protocols, environmental conditions, and any deviations from planned procedures, enhances the credibility of the collected data by allowing for external scrutiny.
