Solution

In correlation analysis, r r represents the Coefficient of Correlation. The coefficient of correlation quantifies the degree to which two variables are related. It ranges from -1 to 1, where:

  • r=1 r = 1 indicates a perfect positive correlation,
  • r=1 r = -1 indicates a perfect negative correlation, and
  • r=0 r = 0 indicates no correlation between the variables.

This coefficient helps researchers understand how changes in one variable might relate to changes in another variable, making it a critical component in statistics, particularly in the field of regression and correlation analysis.
