Variables Definitions

  1. Mean (pre) and SD (pre):
    • Mean (pre): The average value of the data before an intervention or treatment.
    • SD (pre): The standard deviation representing the dispersion of values before the intervention.
  2. Mean (post) and SD (post):
    • Mean (post): The average value of the data after an intervention or treatment.
    • SD (post): The standard deviation representing the dispersion of values after the intervention.
  3. Correlation Coefficient (CC):
    • Correlation Coefficient (CC): A measure of the strength and direction of the linear relationship between the pre- and post-measurements.
