WebDefinition Of Class Interval. While arranging large amount of data (in statistics), they are grouped into different classes to get an idea of the distribution, and the range of such class of data is called the Class Interval. More About Class Interval. Class intervals are generally equal in width and are mutually exclusive. WebInformatics, Reference Intervals, Biological Variation, Evidence-Based Lab Medicine, Biostatistics. Historically, clinical laboratories have referred to reference intervals (RI) as normal ranges and developed them using samples from a “normal or healthy” population. This approach to RI quickly encounters a stumbling block, however.
