Classification in biostatistics is a systematic way of organizing data into meaningful categories to facilitate analysis and interpretation. The fundamental principle of classification is to group data in such a way that patterns, trends, and relationships become visible, making it easier for researchers to draw conclusions about biological phenomena. In biostatistics, classification is particularly important because biological data are often diverse, continuous, or categorical, and meaningful analysis requires structuring them appropriately. Class limits define the boundaries of each class in a frequency distribution. The lower class limit indicates the smallest value that can belong to a class, while the upper class limit is the largest value included in that class. For instance, in analyzing the ages of patients in a clinical study, if one class is defined as 20–29 years, 20 is the lower class limit and 29 is the upper class limit.
