  • The main result of a correlation is called the correlation coefficient (or "r").
  • This ranges from -1.0 to +1.0.
  • The closer r is to +1 or -1, the more closely the two variables are related.
  • If r is close to zero (0), it means there is no relationship between the variables.
  • If r is positive, it means that as one variable gets larger the other gets larger.
  • If r is negative this means that as one gets larger, the other gets smaller (often called an "inverse" correlation).
