## his·to·gram

(hĭs′tə-grăm′)
n.
A bar graph of a frequency distribution in which one axis lists each unique value (or range of continuous values) in a set of data, and the area of each bar represents the frequency (or relative frequency) of that value (or range of continuous values).

[Greek histos, mast, web; see stā- in Indo-European roots + -gram.]

## histogram

(ˈhɪstəˌɡræm)
n
(Statistics) a statistical graph that represents the frequency of values of a quantity by vertical rectangles of varying heights and widths. The width of the rectangles is in proportion to the class interval under consideration, and their areas represent the relative frequency of the phenomenon in question. See also stem-and-leaf diagram
[C20: perhaps from histo(ry) + -gram]
