  "term": "Coverage Factor K",
  "field": "Environment",
  "definition": "In general, a value chosen on the basis of the desired level of confidence to be associated with the interval defined by U = kuc. Typically, k is in the range 2 to 3. When the normal distribution applies and uc is a reliable estimate of the standard deviation of y, U = 2 uc (i.e., k = 2) defines an interval having a level of confidence of approximately 95%, and U = 3 uc (i.e., k = 3) defines an interval having a level of confidence greater than 99%.",
