class boundaries The boundaries for the classes when data is grouped. For continuous data, measurements will normally be recorded initially to some degree of accuracy. For example, if intervals are 1.5 ≤ x<2.0; 2.0 ≤ x<2.4.…. with observations recorded correct to the nearest 0.1, then the class boundaries are 1.45, 1.95, 2.45, etc.
