class interval

a range of scores or numerical values that constitute one segment or class of a variable of interest. For example, individual weights can be placed into class intervals such as 100 lb–120 lb, 121 lb–140 lb, 141 lb–160 lb, and so forth. Class intervals often are used in frequency distributions and histograms to present a large data set in a simpler manner that is more easily interpreted.
