The lower class limit of a class is the smallest data value that can go into the class. The upper class limit of a class is the largest data value that can go into the class. Caption is the upper part of the table, describing the columns and sub-columns, if any. Box-head is the entire upper part of the table which includes columns and sub-column numbers, unit(s) of measurement along with caption.
