A student investigating the effect of aerobic training on VO₂ max collected data from 10 participants before and after an 8-week training program. When drawing conclusions, which of the following would be most important to consider?

  1. Comparing the data with the general population's average VO₂ max
  2. The brand of equipment used to measure VO₂ max
  3. Statistical significance of the observed changes
  4. The participants' previous exercise experience

Consider Option C: Statistical significance of the observed changes

  • Statistical significance determines whether the observed changes are likely due to the training program rather than random chance, which is crucial for valid conclusions.

Other Options:

  • A is incorrect: Comparing to population averages doesn’t directly address the investigation question about the effect of the specific training program.
  • B is incorrect: While equipment quality matters for data collection, it’s not the most important factor when drawing conclusions from already collected data.
  • D is incorrect: While previous exercise experience might be relevant as a variable to control, it’s not the most important factor when determining if the changes observed were meaningful.
